As for the Ustream thing... I'm surprised there isn't a feature on ... yanow, USTREAM that lets users sign up to be notified when their favorite artists are on. Preferably in real time, through like IM or something. I mean, you'd think that would be one of the first features you'd want to put on there.
And if there is such a feature... people need to USE IT and stop making journals every damn time they start streaming. Especially since most users aren't likely to log in to see them until it's already over.
I share your sentiment of the ineffectiveness of journal posts to communicate Ustream info. I am watching over 1,000 artists, and I report that 15% of all the delivered journals in my inbox are Ustream notifications -- nearly all of them over 4 hours old are expired. The influx of these notifications suggests that Ustream may become a prominent influence of the fandom in the near future. This recent volume of interest in Ustream by FA users is why I make the suggestion for coding to accommodate the live-video streaming website.
Ustream has RSS streams -- for archived pre-recorded shows only. There IS a feature to IM Twitter users who are friends of live broadcasts, but the FA user has to sign up to Twitter, find all his/her watched furry artists (hopefully they have accounts too) who are potentially going to start a Ustream broadcast, and have their Twitter set up to IM notify all who are "following" them. Having the whole FA userbase go sign up on Twitter and hunt down and "rewatch" all the artists they are watching on FA for potential Ustream shows, seems a lot of needless and wasteful doubled migration -- not to mention relying upon two external mega-websites not catering to the anthropomorphic niche.
Since it is obviously unrealistic and prohibitively expensive to have FA host streaming for furry drawing videos, and thus reliant on Ustream to host the content, the smart money is on coding FA to notify users of such popular events outside the FA website. If Ustream is becoming very popular with FA users (as indicated by the volume of Ustream journals), it's safe to say the fandom is heading in that direction -- so I'm just making the suggestion here for increased integration.
If I haven't made it more clear in my prior posts in this thread, currently on FA, there really isn't a way for furry artists to just broadcast Ustream to those who are watching them here of FurAffinity that they are drawing -- other then the journals, which are not really designed to intuitively deliver live Ustream info effectively. FA artists need a way to send notice to their watching audiences of Ustream videos, without all the clutter of expired broadcasts filling up the inbox.
