I randomly read old LJ entries once in a while. One time I went all the way back to the beginning of my journal and went forward through each entry in order to tag some, change friends-only/private settings, etc. It was overall not that fun reliving a lot of stuff (I tried not to read much of some of the entries), but some of it was enjoyable and I made myself laugh a few times with own wit and wordplay.

Of course, I've also re-read the zines I did when I was 17-18 years old and, boy, most of that is just downright embarrassing, with a couple little chuckles thrown in. I never let Sharon read them just because I think they're so dumb.
