I have a sweet tooth....but what is blog candy?!

So, I'm still trying to figure out everything I want to learn and know how to do with this blog. This blog will have a variety of posts, including my crafts. I was looking at other crafters blogs today, and discovered "blog candy". I'm still not quite sure what that's all about, but maybe that's something in my blog's future (far future, however)! If you know anything about blog candy, or have any other suggestions or tips to share with me about blogging, feel free to share.
