Recently the author Collin Kelley wrote a blog post that I think lovers of poetry will want to bookmark.
It is a list of poets who are on twitter. Please check it out at Poets on twitter.
I recently started using twitter myself. Although most of my tweets have been about music and my music blogs, every now an then something dealing with poetry catches my eye. You can check out my twitter stream here >> Fitzgerald @twitter
