If there's one thing I learned at MAX this year, it's that the Adobe bug base is alive and kicking and that the Flex team is very focused on fixing the issues they've encountered.
If you find a bug, please file it here. And if you're a dedicated developer interested in making Flex better, please go through the weird UI to find some of the more important bugs and vote to have them fixed. :) My only complaint about this bug tracking system is that it's really hard to wade through the list of issues to find the one you want...voting for them without soliciting your friends and co-workers with a specific URL is a little difficult.
Here's to Flex, the Flex Team, and everything they're doing to make Flex better.
