To blog, or not to blog?

Piggybacking off of Mommy, PhD's post about anonymity, here goes:

I'm having some of the same questions about anonymity, as well as the purpose of blogging in general. I've found blogging surprisingly helpful! First, because I'm able to get support from the few friends I have even if I'm not "around" in person for a few days. Second, it just really helps to vent sometimes.

However, I've started leaning toward the idea of this blog as an online journal. I like the idea of writing about anything I want, regardless of whether or not anyone comments. The problem with this is that there are some things I'd want to blog about that I intentionally do not discuss with anyone IRL. Given that several of my friends read my blog, this would expose some very personal matters, which I would never want to talk about with them (or anyone I actually know). Isn't this weird?? I wouldn't have any problem publishing the issues in a public blog, or even talking about them with perfect strangers, but I would never want to discuss certain experiences with my friends..... I don't understand that, but that's the way it is. I'm toying with the idea of starting another blog that specifically for these *personal* posts, but I have yet to make a decision...I'm also thinking about the old saying: If it ain't broke, don't try to fix it. That is, I seem to be doing okay without having "worked through" lots of old, yucky stuff that's happened, so why bother drudging it up now?
