Netscape support has ended. I remember using Netscape in the early days, part of a package I got from my graduate program. Thing One and I talked about getting into the IPO (talk about missed opportunities: could have made some serious $$ that first day).
I don't remember when I stopped using it, but for a while I used IE and then made the move to Firefox. According to my stat counter, only .1% of my viewers (aka "someone in Ontario Canada") is using Netscape anyway. Still, it's one of those "sniff" moments.
