crawling out of the dinosaur pit

my kids laugh at me when i mix up google, windows, and firefox. i haven't yet gotten to the place where i can confidently say that i understand the difference between a search engine and a web browser. they were otfl (for those of you who don't have teenagers to translate: ontl means "on the floor laughing") when i asked if windows used to be called ibm. (back in my early computer days there was ibm and mac). today there was something i wanted to do on the internet and it required my blog address. blog address? i don't even know what a blog is. so, i looked up "what is a blog? in google and before i had finished typing the question, google predicted what i wanted to know! see? it wasn't such an outlandish question. i found out that blog is short for "web log." an online journal. sounds very exhibitionist to me. then i read something that said if you linked your blog to twitter you would get more hits on your blog. just as i started feeling brain freeze creeping in, my teenage daughter came downstairs and i asked her, "what's the difference between a blog and tweeter?" and she didn't laugh! i think that means it wasn't a dinosaur question.
