There's a hierarchy of social media that many people who don't use all forms miss. I think that our niche as developers and designers drives the social media bus differently than say our average soccer mom would.
Twitter - 140 characters drives traffic via links to blogs and interesting discussions. It can also be a discussion venue between 2 or 3 people.
Facebook - Like Twitter, drives traffic, but can also be used as a forum to post images, etc.
Blogs - Are the driving force that starts our discussions. You have posts that are lists of "other posts", interesting techniques, tutorials, goofy videos, etc. All of these can be shared across different platforms and discussed.
I think that forums like WW should be our little inner circle that we bounce ideas off of eachother. If you're a poker player you know of 2+2. I think they (and a few others) can be marked as the reason why poker has thrived so well during this poker boom over the last 7 or so years. Discussions on hands, strategies, books, etc. are what drive blog posts, play at the tables, tutorial sites, etc.
WW can still be a resource for good questions and discussions, but the focus needs to be on helping build the social media atmosphere. Using it as a resource for future blog posts, or to bounce ideas off of other professionals about techniques (I guess sort of expanding the twitter convos) would be a good starting point.
Moderators need to start by starting threads with a memorable topic. There were a few posts that I remember that were what I would call "epic" by moderators. I remember a few by SuzyUK that really were heralded by all as being one of those that you can always go back to. I'm sure there are other moderators that do the same.
But more discussions like that are necessary to water down the day to day "why is my loop not looping" questions that everyone always asks when they're just starting out.
Why would we EVER want to split the new kids away from the older posters? You guys are our virtual mentors in a way. That would not help out the community at all.
