Few things have given me as much trouble on Linux as Flash. Adobe has shown that it can write good code in the past, but much of their stuff has gotten incredibly bloated. Why on earth should a PDF viewer be as huge, slow, and fragile as Acrobat Reader 8 (a 217 MB tree on WinXP here)?
That old saw has seemingly been updated to: "The Internet treats Adobe as damage and routes around it." I'm glad it's progressing reasonably well.
Cheers,
Scott.
