They are still working, they just don't have breaking news to share atm. The last release was about 10 days ago, so what do you expect? You should visit the IRC channel sometimes, there's more activity than here. You can also ask the Devs personally there.
I personally wasn't expecting or demanding anything that the devs can't provide and I do acknowledge that they cannot be everywhere every time. And yes no news to report is natural at times, it would be unfair to expect that there is something new to report every time someone from the dev team posts something. I suppose I just wanted some form of confirmation that the devs are still there which no one has been able to provide until now. In any case I'm happy to know that everything is well. And yes I'm still buying. Cheers!
EDIT: Oh and I did pop in to IRC yesterday and posted that question... didn't get a reply, or maybe I just didn't stick around long enough
