I own a few and I started doing an internet tv show but its languished because I'm busy building up sites. New episode Labor day weekend. I don't know I'd say they're "hot" but I get demos/mixtapes/links to media every day. I'm building up both ends. Sites that pull in leads/demos/bands/artists, and sites that push their stuff. What would you like to know? I'm starting to think there's a market to sell leads to offline promoters. I get these guys trying to data mine my sites and sending me dumb emails trying to get me to HELP them data mine my sites. Or heck, how about instead of LendingTree, do PromoterTree. Where promoters compete for your band. Band posts budget, promoters bid or something like that. I have no time to implement these ideas... LOL.
A Vagex style bot that supported multiple services could make bank. Heck, charge for the bot and access to the server plus upsell credits. Or sell the server software too for people to setup their own independent regionalized promo bot teams. Sell ads in the software too. All the wannabe rapper kids with a little bit of pocket money would buy it. Which is about 5% of all the wannabe rapper kids. But there's a LOT of them.
