37signals, the company that offers products such as Basecamp, Backpack, and Writeboard, noticed that a plurality of their users use Firefox.
Not real surprising, since 37signals has done a good job of marketing its wares to a techy, early-adopter type crowd, but hasn’t completely broken into the mainstream. It’s interesting to see, though, that Basecamp, their project-management application, has the highest Internet Explorer usage. Good indication that people are using them at work, which is still heavily IE-dominated.
Me, I like Firefox. I probably wouldn’t use IE if we didn’t need it for some of our applications at my work. With Firefox, this blog design is liquid. With IE, it gets stuck in the middle, because IE can’t figure out a simple minimum-width attribute in CSS. Supposedly IE7 will fix that.
