It doesn't have the Golden Girls like the Flex behind the scenes videos, but Boston.com came by the Brightcove office a few weeks ago for a video about development hell and Paris Hilton.
In other Brightcove news, check out a new use of Aftermix, with pages to create and view mashups on snow.com. It's the first off-site use of the application.
I haven't been working on Aftermix lately, but there's a lot of other interesting Flex work going on here... just nothing I can blog about yet.
