If you can believe it, there are actually times when I do delete posts before hitting send. Quite a few. Looking at some of the stuff I've let live, you can imagine how retarded the cut ones were.
I let a lot of stuff by that I know might not reflect exactly well on me, because I want to be as honest as I can. I have to edit other people's stuff all day, so I can't keep from self-editing, but my standards for myself are far more lax
Pretty much what you see is exactly what I'm thinking at the moment, even if that happens to random, unrelated, posting under the influence, angry, self-loathing, contradictory, happy, weird, or otherwise. Weird gets deleted more than anything. Also, I don't like to reply to posts from people talking about the really difficult times in their lives, e.g., death, illness, hard financial times. Everything I type seems overly trite and formulaic, or harsh, or self-absorbed. You know, I want to tell about something that's happened to me that's similar to what the other poster writes, and then I realize they really don't need nor want to hear about it, so I delete it. But then it looks like I don't care because I haven't chimed in, so I feel like I should say something, so I make something lame and keep that about 50% of the time.
All in all, dead posts account for maybe 20% -- quite a bit, when I think about it. I can think of one recent one that is going to join its brothers in the "dude. just shut up and go to bed, you're stoned." graveyard shortly.
