FF Meta for Firefox: http://www.mozilla.com/en/firefox/3.6/whatsnew/

The Typekit blog also lists featured sites with webfonts: http://blog.typekit.com/

There's beginning to be a nice collection of very usable open source and/or freely licensed stuff out there that makes the subscription issue less of an issue.

However, the lack of proper anti-aliasing (at least in Firefox) really turns me off still.

I wasn't aware that WOFF has come to FF, though. Good news!

Can I put my hand down now?

Kernest displays thumbnails of the sites it's serving fonts to.

Just a reminder: @font-face use doesn't require a third party service, so the only way to know - is to check the site's CSS. Honestly I've been pleasantly surprised by the font stacks I've been seeing lately.

I'm currently trying out a couple of weights of Fedra Sans Alt on my own site, as sort of a test. It seems that rendering quality on Windows is a real issue? I must admit I'm not really up to date with all the background; to be on the safe [but still somewhat progressive :-) ] side, I think I'll limit it to titling at the moment, and only in situations of course where fallback fonts are also OK, so that the @font-face becomes sort of a «bonus» for those people who can see it.

This is the OS, has very little to do with Firefox per se.
