I apologize if this is a silly question or if I am missing something.

Are the developers going to continue to update the developer's blog? The last post I see is the one made three weeks after the full launch.

Or are the developers posting updates on the game development somewhere else?

I liked when they posted their thought on the game's progress, but haven't seen anything recent. Thanks for any help and clarity!

We (the players) don't know for sure, only way to find out for sure is to ask the devs. But I do know that one of the devs was on vacation for a few weeks after the holiday. So I'm assuming that in those weeks, plus the week before and after, most time and energy is spent on actual coding. Also possibly for other projects they might be working on beside this.

I don't believe there's another blog or forum they're posting on, besides their Twitter accounts.
https://twitter.com/subterfugegame for the official one, and there they also retweeted some tweets from their personal accounts. (Ron and Noel)
