I stumbled across this list enumerating the qualities of good blogs. A couple highlights:
Good blogs reflect focused obsessions. People start real blogs because they think about something a lot.
Maybe even five things. But, their brain so overflows with curiosity
about a family of topics that they can’t stop reading and writing about
it. They make and consume smart forebrain porn. So: where do this
person’s obsessions take them?
When I first started this blog, I wanted to make it all about fishnet stockings. But then I realized that there’s only so much you can say about fishnets (i.e. “those look HOT!”) before you start repeating yourself. So I decided that I needed to branch out in other directions. But even when I’m blogging about disability issues or Battlestar Galactica, I usually have fishnets on the brain.
Another tidbit:
Good blogs try. I’ve come to believe that
creative life in the first-world comes down to those who try just a
little bit harder. Then, there’s the other 98%. They’re still eating
the free continental breakfast over at FriendFeed. A good blog is
written by a blogger who thinks longer, works harder, and obsesses
more. Ultimately, a good blogger tries. That’s why “good” is getting rare.
So that’s my problem. I might be compelled to try harder if I wasn’t always so damn distracted by persistent thoughts of women in fishnets.

Ahhhh the workings of the male mind… thank you for clarifiying that … I always suspected as much but to have a real true life male admit it! refreshing LOL
Great one mark!
