Actually, there already is a service which connects advertisers with Twitter users for paid advertising, but I can't remember the name of it for the life of me.

Actually, there already is a service which connects advertisers with Twitter users for paid advertising, but I can't remember the name of it for the life of me. Fortunately, it hasn't caught on. There isn't much incentive to sign up; advertising makes you look like a tool, the money available is bound to be small, Twitter in general doesn't incur overhead, and people mostly use Twitter for fun. Perhaps Twitter make it against the TOS, but even that seems overkill. The "viral" nature of Twitter should keep the negative effects of advertising to a minimum.
