Hey - Russ approved!
Anyway, yep - we have new icons and a way to access them (and the tinkering has just been finished). I haven't counted them, but there is in the neighborhood of 140 icons, 3x as many as before. There should be an icon for every conceivable topic now.
The old "legacy" icons will remain visible for the threads to which they where chosen - they just can't be chosen for furture threads. This has to do with the way the new ones are sorted.
Yep - they're sorted, which means finding the right one should be much easier.
