I think communities will need to keep evolving. Blogs, for example, greatly reduced the willingness of forum members to write long, detailed "how to" posts. For years now those kind of posts have mainly ended up on blogs where the opportunity for personal branding and ad revenue is greater.
Twitter has, in turn, dramatically cut the use of blogs for very short posts. In the past, a blogger might post a dozen or two times a day, often with nothing more than a random thought or a cool link to share. Now, those end up mostly on Twitter.
Let me turn the question around, tangor... how do you see independent communities changing, and what thoughts do you have about how to keep them relevant to members?
