Well, normally I wouldn't spend a lot of time discussing my own writing here (plenty of time for that in my own thread
), but since V and coz brought up it up, I might as well try and explain the way in which I continue with my rather lengthy story.
First, I think it is very important that every post do a few critical things. Every post must advance the plot, it must provide added insight into at least one character, it must connect with a previous post, and it must connect with a future post. Allow me to explain in detail. (Warning! Verbosity Alert! Danger! Lengthy post ahead!)
1) Advancing the plot: Basically, something must happen during the post, and it must be something directly related to the story. This is just a detailed version of "Every post should add to the story", but its trickier than it might seem at first. Advancing the plot does not mean chronologically moving the story ahead. A flashback can advance the plot just as much as a a regular scene. A side story about some minor character can also do the same thing. The key is to NOT post purely information segments where nothing really happens. (Note: This is why I use Historical Extracts for infomration stuff. My readers might need the information, but I don't clutter up the actual story with it.) It's ok if there is not alot going on, but SOMETHING must happen. Note that it is ok if what is really happening is not immediately obvious to your readers. If your readers trust you, you can get away with seemingly innocuous posts that turn out later on to have been advancing the plot forward. (Note: There were some segments in my writing that readers found a bit odd until future parts were posted and they went back and saw how it was moving forward in the story. Of course, this is something to be done sparinginly.) This is a time honored tradition is movies as well. The movie Fight Club gives us plenty of this "sneaky" plot advancement.
2) Insight into a character: Your characters should always be doing things and saying things that shed more light on who they are. It's not enough to just advance the plot; your characters have to "advance" as well. In every post, a little more of at least one character should be revealed. Alternatively, a character might begin to change in a post. These revelations and changes don't have to be dramatic. In fact, pacing the revelations and changes out over several posts is the key in longer writing. If you reveal everything in one sitting, you don't have alot to do in future segments, do you? If a character is completely static, he will get boring over the long haul. Also, having characters interacting with other characters is a sure way to getting this done. This is why I often employ pairings of characters. Makes revelation of character and change flow more naturally from the pen, err, keyboard.
3) Connecting with a previous post: This sounds easy. Just make sure the action follows from one post to the next, right? Well, yes, but its more complicated than that in longer writing. If you are doing a work that will cover 200 years of history, you MUST tie it all together. And tying it all together means more than just going from post to post. "Historical" events that happened a long time ago in the story will be referenced by characters in the present day, even if only casually. Characters also have memories, so if they are 60, and you were writing about them since they were 20, you have to constnatly reference old material. This isn't boring; this is actually a way to kep readers fresh and involved. Your readers will recognize and appreciate the occassional references to things they read before. It gives them a sense of belonging to the work. As such, a post can connect to a previous post, but that previous post may be 200 or so post ago. That's just fine, and it gives your readers a reason to remember all sorts of things that happened in the past.
Now, for those wondering, how does an initial post connect with a previous post? The answer is to provide a false background for it to reference. Even if you haven't written it, these characters have pasts and memories, so fill in some gaps. The same goes if you are starting something new with characters who won't know immediately what's been going on in previous posts.
4) Connecting with a future post: Just as a post must connect with the post, it must connect with the future. Of course, you probably haven't written the future posts yet, but that doesn't mean you can't connect with the, as yet, unwritten future. Connecting with the future usually involves leaving a "hook" of some sort at the end of a post. Basically, you leave some unifinished business for the characters. This fits well with advancing the story. You advance it, but not too far. The best examples of this on TV are, of course, Soap Operas (I have no idea what you Europeans call them). Of course, you don't have to be as dramatic as they are (and you probably shouldn't be, most of the time). But by suggesting something that will happen in the future, your readers have a reason to come back. And YOU have a reason to keep writing. This is a rule I'm not always so good at following when I am in the middle of a story, but I get better about it when I get towards the climax.
While I've advertised these rules as useful for lengthy writing, there is no reason they can't be used for shorter works to. The format of the forum dictates an episodic style. As such, we must fully exploit the advantages of such an arrangement.
Another minor consideration for those who even think about attempting a long work. Just because you want to write a full length novel covering 400 years of history doesn't mean you have to write just one story. Breaking it up into smaller story chunks is probably the best way to do things (unless you're doing a collaberative project. Then all bets are off). As LD and MrT found during the course of their lengthy projects, readers here are not very tolerant of single lengthy stories. This is not some sort of failing in the readers, nor is it a failing in the writers. I think it is a natural consequence of how this format of writing works. I may be misquoting, but I think it was Peter Ebesen (whose name I never can spell properly
) who mentioned that if he wanted to read a full length novel, he'd go buy one and sit down and read it. Most folks here only have limited time for reading, and it's asking a lot of them to stare at a computer screen for hours on end to read things off a website. It is the truly rare and dedicated fan who prints up his/her favorite AARs and marches off to read them for hours after work. (By the way, such a fan is well worth keeping around and being cordial to, as they tend to keep very good track of what you've done.) Heck, in my hey day of reading, I was only able to because while I was at work, there was no real work for me to be doing most of the time. The point is that bite sized story chunks are more accessible to the average reader than lengthy novel style writing. Neither is better, but there are consequences for choosing either style.
