Recently, I discovered carnivals... blog carnivals. These are traveling digests of blog posts on a certain topic. So, as a writer, you can submit an entry to the host, and they may publish your link, which could increase traffic to your blog, and, ideally, expand the conversation. To the reader carnivals offer exposure to many blogs on a topic of interest. Apparently, there are tons of them out there.
So, I submitted a post to the current Carnival of Education, and what do you know? The host included my link. That's cool-- who has never desired the life of a carny, even for just a minute? And, there I am in the company of other teachers who are working hard at leading the examined life. Awesome. Check it out if you have time.
