the truth is in the details

Because I have a lot of time on my hands, I've been "surfing" the web again. More specifically I've been taking advantage of the "next blog" button. Here's a couple of things I've noticed:
1. There are lots of blogs with only one posting on it.
2. There are lots of blogs that are basically just ads pretending to be something else.
3. There are not as much porn blogs as I thought.
4. Even though it's supposed to be random, I keep getting the same couple of blogs over and over again.
I don't know if this something that I want corrected because it's interesting to see what other people are thinking/saying. It's also interesting to see how we really all sound pretty the same (I included myself in this category).
