The latest iteration of Joost, the once-hot, now decidedly not video startup from the people who brought you Skype, will work in your browser — but only if you download a plugin from Joost. And while Joost struggles to find good content, Adobe is rolling file sharing into its Flash player, beating Joost's new plugin to the punch. NBC has worked with file-sharing content delivery platforms in the past, and Hulu — a site backed with quality content — uses Flash. I'm sure the Joost developers are tech whizzes, but even our journalist math puts them on the wrong side of this equation. (Photo by Job D.)
