Blogging has already given the language a few new words. Starting with "blog" itself, and of course, blogger and blogging, going on to hybrid creations like blogosphere, blogroll, moblog, and cyborglog (glog for short).
We obviously have too much time on our hands, so here's some more we thought up. (You venture capitalists can queue up on the right, please.)
Collablog - a term we invented to replace Group Blog (hasn't caught on yet *grin*)
Kleptoblogger - someone who uses your links without attribution
Bloglugluglug - too many blogs, too little time, drowning in blogs
Hobloglin - blog reader who makes mischievous comments
Glob - typo on blog that the blogger attributes to dyslexia, not to too many hours spent staring at the monitor
