I'm proud of the team I worked on, but have ambivalence for the company.
I was on IE 1.0 thru 5.0 (roughly '95-'99). It was a great team and in many, but not all ways, I think we made a great product. What happened on IE 6.0 was a tragedy. I wasn't there, but neither was most of the team that worked on IE5.
The only bright spot of that tragedy is it helped open the door for Firefox, which I love and have used for years.
