Well-known WebmasterWorld member, reseller, started a thread at WebmasterWorld named Possible Shift in Google-Webmasters Communication Policy! Reseller says;
I have noticed in recent months a remarkable shift in the way Google employees communicate with the webmasters communities.
For one reason or the other the Googlers have stopped posting weather reports about the new infrastructure. No more posts explaining critical changes on the serps. No more talking about specific DCs as they use to do. No more chat when it comes to Google serps and possible changes which are so clear and obvious to even novice webmasters. The only thing we have been hearing is the famous "Data Refresh".
Soon later, GoogleGuy comes in and argues, "I think that there is a lot of good things we've been doing for communication with webmasters lately," listing out a few key things. He then gives some specific advice and continues by saying, "I do think that we'll be discussing data centers more toward the end of the summer, if I had to guess."
Then we had Matt Cutts post himself at WebmasterWorld, saying "Maybe it's time to do a miscellaneous question thread on my site, too? " Which leads to this and SEO Answers on Google Video at his blog.
Overall, I think Google is only improving at Webmaster communication.
