Blog = Web Log
Basically its exactly what vangend said, its a daily online thingy where you post whatever every day. Some people use it as an online diary, others... well, have other uses for it
I plan to do a bit of both.
I dont read any blogs, other than stileproject.com occasionally (which isnt really a blog!) so i'm no expert
Thanks everyone for the great response I'm sure I'll find what I'm looking for in one of those
