I certainly did. I used a lot of features in Netscape that IE never had, and at university it was _the_ browser used on campus in the late 90s.
IE 5 was a buggy browser lacking a lot of features, but was used often by people not building things online. And forced on people by bizarre site requirements. Though this came worse with IE6.
Microsoft was embroiled in legal issues of their browser at this time, and anyone with a sense of logic (most programmers) could see being locked into one piece of software instantly degrades the value of that software.
Sept 2002 was when Phoenix was released.[0]
IE 6 came out only a year before Phoenix.[1] And you if you were involved with Slashdot back in the day you were tracking browser usage as a daily trend. Phoenix was doing well.
