… I observed the following:

1. The vast majority don’t know how to write properly.
2. A lot offer SEO and blogging tips on wordpress.com or blogger. People also offer tips on how to get easy money over the internet on these services.
3. Most don’t use the MORE tag when posting videos or any other flash content.
4. Blogger is used more than wordpress.com although blogger sucks when it comes to design and functionality.
5. Loads of people use widgets like calendar and categories. As far as I know, these two are considered useless. Also have seen a lot of flash clocks.
6. Some can’t read. On the first page you have a post stating you are not accepting link exchange requests and someone leaves a comment (in romanian on an english blog ) on your latest post (without any link the the post’s topic) while there’s a nice ‘Contact’ link in your blog.
7. The easiest way to make a blog is putting miniclip games on your site and naming your site something-containing-the-word-games. This can be done with or without your own domain. In the case a domain is used then it’s double trouble. You just wasted some money.
8. Most blogs (on blogger and wordpress.com at least) are made in a moment of boredom.
9. The most common description in About pages is “I am me (and no one else)”.
10. Some have captcha + moderation + akismet activated on comments.
11. Right-click protection is so ’95. If I want to steal something from your site, that will not stop me.

Did I miss anything?
