I used AIM as a kid, now I use Pidgin.

I used IE as a kid, FF as a teen, and now Chrome.  

I used to download things from Kazaa.  Then Bittorrent.  Now DC (sort of).  

I used Windows XP as a kid.  Then I thought I was awesome and tried a ton of different flavors of Linux.  Now I just use what's easy, which is Vista and/or Ubuntu.  

I had a LiveJournal.  Now I have a blog.  This somehow makes it slightly better I think?
