That's true. There are no official posts from the devs as far as I know. You are actually raising a good point there!
If you are looking for a place where you will get this information, join the Gridoin Slack channel. There are the devs and the grcpool and gridcoinstats admins around and also a bunch of other great people!
I have now joined the slack channel, and a few more, they are very informative and have also installed a Gridcoin client to run on the testnet.
So I'm trying to help a little :)
