How technology savvy am I, really?

While I try very hard to keep up to date on the latest technology (okay, that's a lie), I'm still a bit confused as to what the exact definition of "blog" is. I mean, why not call it "online journal, accessable to others" or "personal message board" or something like that? I guess I'm just a little unclear as to where the word "blog" came about. It's not a word that was ever used for anything else, then was applied to mean what it means now. Does that make sense? Anyway, I guess I do want to try to keep abreast of most new technology, although it's very hard, being a stay-at-home Mom. I mean, there's no real need for me to rush right out and get the latest Blackberry. (And why do they call it that? I prefer cherries, or even strawberries... If I got one of those, couldn't I choose the flavor myself?) I recently got myself a PDA (still not sure what those letters stand for--I always used them as Public Display of Affection!), though the one I got is so cheap, I rarely even use it. Believe me, despite being a SAHM (Stay At Home Mom), I do have a lot of different things on my schedule to keep track of! There's volunteering at school, Brownie meetings (I'm co-leader of my 7-year-old's troop), babysitting at Jazzercise (it used to get me free classes, but now they're 1/2 price, which is still a good deal), plus my work on the Art Show committee for my Church, my 7-year-old's CCD classes, homeschooling and occasional play-dates for my 4-year-old... AND, of course, my few weekly shifts at the local grocery store where I cashier. So much to do, so little time to blog. Yikes! Look what I've done... I blogged after all! (It almost sounds like I did something dirty, doesn't it?)
