A purpose?

So, I'm not quite sure what my intent is in having a blog, I'm sort of a late bloomer in the whole fad anyway. I want to make it clear that I'm not trying to be the next "Pitt girl" even though I'm going to try to remain anonymous and I do live in Pittsburgh (incidentally most of my posts will be about life in this city). I think I'm just looking for a way to vent, so that I won't need an anxiety pill at the end of the day, hopefully this will help. I don't think anyone will actually be very interested in this, truth be told I think blogs are vain attempts at getting attention. I mean, why on earth should one think that anyone else should give a damn about what one thinks or feels about anything? Although given the popularity of "Pitt girl" I suppose some people are interested in the ramblings of another person, perhaps it makes them feel better and less alone.
