Does your blog have a Creative Commons license?
Allowing others to share your posts increases the conversation out there in the biblioblogosphere.
To add a license (and there are several to choose from) visit Choose a License to get started.
If you're on Twitter, and your blog has a Creative Commons license, take part in the Creative Commons challenge (spurred on by Dave Lester) and announce your CC-love with the hashtag #ccchallenge. If you're not on Twitter - how about writing a post about Creative Commons and adding to the conversation?
