If you look at the bottom of the right-hand column on this site, you'll now see this yourminis widget:
It's displaying the top videos on Brightcove.com, but you can change it to display videos from different categories. You can also change other properties, as I changed mine to fit into the column's width.
See the original Brightcove widget here.
On a side note, since most people are still coming here for Flex information, I wanted to point out again that I have RSS feeds for both the Flex and video categories. But I'm happy if you keep reading all my ramblings.
