What the heck is a blog?

So, I'm new to this whole blog thing. When I first heard the word "blog" a year or two ago, I didn't even know what it was. I heard people talk about blogs, and I knew it had something to do with computers, but other than that, I was totally in the dark. Not a big shocker, as I am not the most technologically savvy person. I was the last one on the block to get a cell phone, DVD player, digital cable, digital camera, IPOD (which I still probably wouldn't have, but someone else bought it for me)....and the list goes on. I remember asking my friend K what this blogging was all about. She told me it was a web log or a journal online. The idea of an online journal sounded kind of interesting, but the word "blog" bugged the crap out of me. Not sure why it annoyed me....it just did. In fact, lots of things annoy me. Which is how my blog ended up coming about. My friend that helped me out with the definition of blog, also encouraged me to start this one.....I could write about all the things that annoy me, as well as other stuff. So I'll give this blogging thing a go and blast into the 21st century (albeit a little later than everyone else).....we'll see what happens! I'm actually looking forward to it.
