If you like to submit your poetry in the USA and around the world, a good resource for literary and poetry publications (web & print) is Duotrope. It has a monthly or yearly fee, but has free trial period to test it out.
Some new literary and poetry sites: Frontera (Spain), Rise Up Review, Troubadour [Picaroon Poetry] (UK), and Us For President. Before submitting, be sure to read guidelines and look for any geographic restrictions on submissions.
A site I read periodically is Anti-Heroin Chic.
