Ochocinco has gone one step beyond that. He's having a contest on Twitter each week to fly a fan to a Bengals game to be his guest tweeter.
If you are very patient, (lots of deadtime at the beginning of video) you can hear his offer around the 7:45 mark, via Mashable:
Giving the keys to your Twitter account to a contest winning fan is a whole lot of trust, but perhaps it is worthwhile in promoting Brand Ochocinco. This season he will have the pressure for his onfield performance to match his online exposure. If he can't find the endzone, how is he going to get good tweets?
In the video, he also says that in the Bengals' matchup against the Rams, he is going to be playing some quarterback. He's already played kicker this preseason, so quarterback isn't much of a stretch. I guess opposing teams need to follow Ochocinco's social media stylings to know what to expect, unless that is a smokescreen.
