But, Blogger makes that a little difficult to do. The default templates are "nofollow" and if you leave a comment, the default is a link back to your profile instead of your blog.
I followed Blogger Buster's tutorial on getting rid of the "nofollow" parts of the templates on both of my blogs to allow 'linklove' for everyone that chooses to comment. It's easy to do.
How to do it. When you leave a comment on my blogs and any other Blogger blog, choose the "Name/URL" option instead of accepting the default Google ID. The name you leave will be what shows up as the linked text. The URL you leave is the address to your blog, and it needs to be a complete URL. You have to include the "http://" part of it. For instance, this blog's complete address/URL is http://bumpypath.blogspot.com, and that is what I enter whenever I leave comments on other blogs.
The other thing I've done is add a Top Commenters widget. The most frequent commenters during the last 30 days will show on the list and it also includes a link back to the address you used to sign your comments. If you use the default Google ID, it will only link back to your profile and not your blog.
So, go ahead and take advantage of all the linklove/backlink opportunities and use the Name/URL option when leaving comments on Blogger blogs!
Hope this helps.
