Sometimes it's interesting to dig out older blog entries:

Jason Kottke, March 1998

Dave Winer, April 1997

As for my own blog... here's a history of URLs my main site – mostly, a "homepage" not a blog. I moved from Geocities in 1997 to Xoom in 1998 to my University server afterwards, and finally to outer-court.com. (I was using Stylesheets and HTML Strict back in '98, but no XHTML yet.)
Most of these are ghost sites now:
