Hey,
This might have come up already, but I think it would helpful to have a single page that collects (or at least points to) all the available add-ons folks have put together for TextMate, such as bundles, syntaxes, snippets, and so on. A two-line summary of what it does (with screenshots where possible) would also be great.
I agree that the power of TextMate comes from unlocking its _insane_ amount of configurability. But, I also suspect that some of the nay-sayers--especially those less experienced with the power of a shell--would be much more inspired if they saw what they could *do* with TM (without having to build the actual widgets themselves).
For inspiration, I think Alcor has done a nice job with [Quicksilver's plug-in page][1], which folks can sort by alpha, popularity, or update freshness. Best of all, users can click to install any of the plug-ins right from that page. Takes a lot of the mystery out of the process.
Just one data point. If ya'all need help with bandwidth or what have you, please let me know how I can pitch in. I am, as the kids say, a fan.
