I think the lack of control we have over MB is stifling and unfair. We're the ones who use this site, yet we have so little control over it. I know it's irked me for a long time now.
Had it ever seemed possible to do it in a way that keeps the community intact, I would've organized a mass exodus to a new forum a long time ago. I would've asked members to move their journals, reviews or other beloved threads to the new site and delete them here to quickly get content at the new site and hopefully climb the google ranks quicker .. or to move to a forum which has already been around a while so that it's not a no-man's land and an influx of members could be expected in the future.
In the age of information, ignorance is a choice.
