I was blogged, six months ago!

I thought it was fun to notice that somebody blogged a page on my homepage (now very old) a few months ago... Actually, that's not a blog entry, that's just a copy/pasted bookmark! Well, I guess that's not such a big difference - or is it? If it isn't, then why haven't people come up with a combined technorati and del.icio.us, why do we think of these as different things? ;-O

PS: Sure, cauz it's just SO easy to del.icio.us something that you do it potentially many times a day - while you probably blog (properly) less frequently. Still, why two systems?
