My current Blog is on: Mac.com.
The most recent blog before that was built using Apple's iWeb and is hosted on (a different part of my) .Mac saving me bandwidth and server space: iWeb Blog
Prior to that I hosted my own Movable Type blog on my server: Movable Type Blog
And before that I blogged on our own custom made blog system. It goes back to mid 2003 and is archived. This is where the hyperwords system first appeared. It was a prototype. It may be slow (it was a test-bed for hyperwords work, originally all the hyperwords work was on this blog, and only on this blog). Some features will not always work:
2003: June, July, August, September, October, November, December.
The first blog I wrote was a basic HTML diary online at Invisible Revolution.net which is still accessible.
Well, you could say that my first site, first at rahul.net and later on liquid.org was blog-like in that I posted articles quite often on them.
