Recently an independent site focused on promoting ideas and discussions for the Lotus Community was launched. Mark highlighted that Microsoft have launched SharePointPedia. So is this the beginning of the end of traditional forums and discussion groups for product based communities? For me the key benefit of both these sites is the ability of the community to promote content. I suppose time will tell on which forums win. The key for all these forums is to have a purpose and actually deliver benefit both to community members and the manufacturers / products. In this case I would be more willing to participate in the SharePoint community simply because it is a vendor sponsored product so I can be more confident someone is tracking the content and talking to the product managers about interesting content.
