In regards to the following comment from Linda: I read a blog which mentioned using Trackback. What is it and how do I use it to connect my blog to others?
Trackbacks are essentially another piece of conversation between sites, particularly blogs, where someone can see connections from one blog post to another. For instance, if you linked to this blog somewhere else on the web, and I was keeping track of trackbacks, I would be notified that the link was created. Likewise, if you visit a blog that has trackbacks, you'd be able to see where the blog was published elsewhere.
Here's another blogpost about adding trackbacks to your Blogger Blog!
