Not that I like to encourage competition among poets - or anyone for that matter - but slams promote the words and I got no problem with that for sure.
Simon Toon's got "Slam Idol" - a regular podcast / slam competition HERE.
Submit your mp3 and have at a bout of Internet poetry wrestling.
To enter the competition, email your mp3 to simon.toon at macmail dot com.
4/30/05 UPDATE: I've got "Compost Thunder" entered in the May competition - vote for me!
