Hey Gigawot,
Thanks for the liking the tool. While it true that new features has stopped for the moment, the service is still up and running for those that want a taste, and will be for the forseeable future. Also, since the service is open source, it is possible for those interested to contribute (though it may be a bit tough to get into the code, so I don't blame them if they're unable to -- but I'll help anyone who is interested)
Development hasn't really stopped -- it has shifted. Having a website where users submit their save games is limiting as it decouples the save from the game. Users complained that they saw country tags and not names (eg. "FRA" and not "France"). On a website users aren't able to see a map of the world and see a cool timeline. And there are other limitations that would essentially mean me having a bunch of installation of the game (including mods) on the server, which is too much work.
Current development is focused on creating a desktop client for users to explore their save game (normal and iron man saves work at the moment!). They get the benefits of localization, no waiting on an external service, and they can interact with other game files such as a map of their save. If users want to share their save game, it is planned to have a "Create Permalink", where their savegame is uploaded and anyone can access it with a link (much like it is today).
Anyways, that's the update. I shifted development because my own needs weren't being met, as I thought they would. I'm still open to the thought of adding more features to the current service as a stopgap.
