FAQ
Q: Why am I limited to two thematic categories for my blog?
A: In the past we had no such limit, and several bloggers added themselves into categories that were only very distantly related to the real focus of their blogs. This made filtering by category meaningless for advertisers. Please select the categories that best describe your blog's focus and your audience's interest. Note that you can join an unlimited number of blog hives - as long as the respective hive managers decide you fit their requirements. A lot of our sales occur via hives, so be sure that you apply to join all the relevant ones. For more info, see this FAQ item.
