A call to arms:
OK, so it's not the noblest cause, but why is Safari still the bastard child of browsers in terms of web app support? WebKit is indeed superior in terms of standards compliance than most other browsers and it's now available on Windows, and of course the iPhone. Yet I still have so many issues with major sites.

More than a year out from the inception of Yahoo's mail beta, Safari is still blocked (unless you use the Safari 3 beta -- and that works OK until you try to modify options and such). I have ridiculous problems with gmail, like not being able to use the 'delete all spam messages' quicklink. Google Documents and chat within gmail are also unsupported. Akin to the Google spam link issue, attempts in Hotmail to use the quick-delete feature for spam are unsuccessful -- I can only get that to work in Firefox. As I type this into MovableType, it's likely that a menu feature will glitch out on me because I'm in Safari... This is madness! What am I missing? I'm sure it has a lot to do with Javascript issues, but what the hell?

I should add that, yes, I am a mac user, but for quite I while I've used Firefox exclusively. I am finding that it is really just too slow to be useful anymore, especially at work on an aging G5. All the web developer extensions in the world aren't going to eliminate my need to have pages pull up quickly and have my browser behave reliably with multiple tabs open... It seems, for now, I am stuck between a rock and lousy browser support.
