We have a fan blog!  We didn't start it--I mean, we're fans of ourselves, but that might be a bit much.  Instead it's kept by a longtime user of FogBugz who has a background in usability testing, and in a recent post he gives FogBugz a theoretical makeover.

He proposes some interesting ideas that are worth a look.  I especially like that he appreciates some of the hard design decisions that go into keeping an interface simple and easy to use, and yet still providing all the functionality customers want.  For more in that vein, you might also take a look at his post on possible FogBugz 7 features (just remember those aren't our promises!).

Drop by the blog and let him know what you think of his FogBugz design ideas.
