Forum Moderators: open
I think there are many like myself who do NOT want to follow the info in the above suggested thread #1 and also many who do not want to read about postings concerning the above suggested thread #3.
An algo-based thread would be interesting but might be difficult for the mods to continually weed out all the 'my site got PR zero' etc. posts.
My 2c worth.
I would say that split the discussion into the following :
1. Official Update - Let this be only as an announcement. Once the admins/mods confirm the update, they can lock the thread and should be allowed only for admins/mods to add any message futher and also as a bonus the poster who announces the update gets the chance to make further posts in this thread. Will be lazerzubb? :)
2. Positives from the update - Discussion around what are the algo changes that helped people to improve their rankings.
3. Negatives from the update - All the PR0/spam complaints go here
If this seems more work for the mods, Brett could get an additional mod just for the update threads ;) Just kidding.
Or for those who think this is asking for too less, what about a forum exclusively for Google Dance/ Updates? ;)
