I find it ironic that this sub sometimes serves as my makeshift blog
Do you write on it as frequently as a blogger would write on a blog?
Not that often. But sometimes I discuss emotional problems relating to my friends and of course, having fun.
If that's what makes you happy, go for it!  However, just be careful about sharing too much personal information on the interenet.  That might come back to haunt you!
I'm ok with that. A blog is a good way to vent out your anger and emotions.
You're right that it's good to simply talk or write about things that are bothering us, and as long as people here are willing to listen, you should feel free to keep posting.  However, it sounds like you are saying that you're okay with the risks of posting personal info, and I have to warn that the problems could end up being severe.  You can talk about whatever you want, but don't use real names or identifying info.
