Micro.bloggers can submit whatever section of their blog that they want, whatever they thing will most engage readers. So, for example, if you have just a category for long form posts you can submit that category. Likewise, many Microbloggers have two blogs, one for long form posts and one for micro blogging. Submit one or both, the choice is yours.
The main idea is to get people from outside the Micro.blog social network exploring our blogs like you would with a conventional webring.
