The answer, I think, is in creating a platform where there is relevance for communities. I was talking with a friend recently who put it simply. "Yahoo! groups are a core asset of the company" yet he did not understand why they do not leverage that community to build content channels! Examples abound, a special interest group for instance can share content and mash it up. And that would make it a better targeted group for adverts....This is a very good point. The Yahoo! videoblogging group is over 3,000 people who exchange ideas in the forum, but don't utilize other parts of the Yahhoo! enviromnent. Whith Yahoo's recent acquisition of JumpCut, maybe there can be som synergy there.
Have you used JumpCut?
How do you feel about editing video online?
Do you prefer computer based editing tools like iMove, Windows Movie Maker and advanced tools like Final Cut Pro?
