Keyword Luv is a WordPress plugin (I don't think you can use it on Blogger but I'm going to check on that and update later) that allows you to leave a comment with a "dofollow" link back to a blog or article and by typing "@your anchor text" behind your name, search engines will recognize "your anchor text" as being the keywords that identify your blog.
I have used this for my blog before (my main blog) and I plan to try it for a few of my articles as well.
Here are some of the blogs that have Keyword Luv enabled (just make sure that you leave valuable comments - none of this, "Great post" BS!):
