>Also content will be more valuable than ever before...

And this is the key...Content has always been the most important element of SEO...You need "something" to promote.

And I agree, it will become even more important. I still feel forums are the way to go as you can get tons of user generated content.

But getting a forum going is a major chore. I've tried a few forums. The only ones that were successful were ones I "added" to an existing site that already had traffic. I've tried starting a few other forums from scratch and haven't been successful.

Also reusing (repurposing) content will be essential by converting it to different mediums.
