How about blogging around poetry and foster a community of poem-lovers and poets. Your blog would share original poetry, and interviews with established poets.
Publish analysis of notable works in poetry. Gather and share tips for improving poetic techniques, and resources for aspiring poets. You can also have a feature to encourage readers to submit their poems and maybe host competitions or featured-poet spotlights. Not many have thought about this, yet. And your blog can become a haven for poets and readers.
