What would you like to know? I have an ongoing blog built with Movable Type (link below in sig...I just finished a *major* design/recode effort on it...), and they are fun, contagious, time-draining/consuming, and at times a monkey on your back!
There are some free blog sites out there, just a matter of what features you want, how much you're willing to put up with ads, etc.
You can
start here to find a free blog system/host.
Cheers,
