Here are the weekly blog hops that I take part in. If you don't know about blog hops, they are a good way to get followers. Basically, you add your blog to a list and if someone follows you, then you follow them back. Also, you can go through and follow as many blogs as you want, and they will follow you back.
If you know that one of these isn't going on anymore, please leave me a comment so I can take it down. Also, if you know of a hop that isn't listed here, leave a comment so I can add it! :)
