The streaming video is great, and it has finally enticed my lovely wife into sharing the falcon semi-addiction I have experienced for the past seven years. The accompanying staccato, twitterish chat, however, makes me long for the insight and substance of the old yahoo-based forum postings.
I personally haven't gotten involved in the "social streaming"...can't access it at work & it interrupts my video feed at home. I'm sticking with here...the chat feature (when we remember to use it) works very well...and I've gotten used to the way this forum works. When I have a lot of catching up to do I'l use the unthreaded version, which is more like the old Yahoo board-just takes a bit more scrolling since there's fewer posts per page...
