Next blog

Ok so at the top of the page on blogspot you can click next blog. I have noticed they tend to be somewhat related to the blog you were looking at. So if you are looking at a family blog or have a certain religion as a theme odds are good you will get a family blog from someone of the same religion. But as you continue to click next blog it seems to base it on the new blog for a similar one. And then at some point either it gets confused or bored and starts giving you random blogs with reviews of sex books. So now I am trying to figure out if it really does try to match for a bit or if there are just lots of people with family blogs....
