Mefeedia is an awesome service I heard about on Rocketboom which is very similar to RSS aggregators like Bloglines and Rojo but targetting the emerging market of video podcasts (or videocasts, or vlogs, or whatever you want to call them). In this way, it is similar to my favorite podcatcher/podcast directory, Odeo. Unlike other videocast aggregators, there is no need to download videos as they are streamed right from the browser. I currently subscribe to about 10 different video podcasts so I have a few gigs worth of video just from that, so it’s nice to finally just be able to stream content. The interface could use a little work as it’s not as clean and intuitive as Odeo but there is lots of great content, and you can tag videos, send them to friends, and do a few other cool things. Additionally, you could subscribe to your member feed in iTunes to gather all those videos if you wanted to transfer them to your iPod. Mefeedia is totally free.
