The penguin guy made a really good point. I've seen a lot of these blogs and not a lot of them I would visit because they just talk about how to increase blog traffic, but they have no blog traffic. Clicking on each other's ad links is against Adsense's policy, you get banned, and not a lot of people are willing to do it.
I have an idea. I'll start, and in the replies we will say WHAT OUR BLOG IS ABOUT and WHAT KIND OF BLOG WE WOULD READ. That way we'll get a sense of an audience. There are a TON of people here and if we find a reply about a blog that matches what we would want to read, then we can follow it.
My blog is sadly all over the place, but I'm gung ho about it and I update 3 times a week. I have narrowed it down to my trials in life and how I go about fighting them. I've been through a lot and because of this I consider myself a very strong person. There are weak people out there who need help. I also try to be funny because everyone loves to laugh.
I would read blogs about survival horror video games, becoming a vegan, food, and ones that make me laugh. Mostly ones that make me laugh. Webcomics are indeed awesome.
