So if you wanted to join Twitter, you could follow the 'day to day' of porn personalities such as Larry Flynt, Jesse Jane, Eon McKai, Nikki Benz, Jenna Jameson (well, actually it's an obvious PR account), Belladonna, Sasha Grey, KumiMonster, Dana DeArmond, Andy SanDimas, (NSFW) Bella Vendetta, Sinnamon Love, Emily Marilyn, Stoya, or Tony Comstock.
The normal people tend to be the dirtier ones, by the way - they're just harder to find. Not to mention all those other 'normal' people who use the service, too. Sex and the Tweet isn't a new idea, and it's on the rise - perhaps even moreso as sex workers, international fetish models, dominatrixes, tech savvy porn stars, adult companies with marketing departments, hip porn directors, sex toy makers, and yes, even sex educators have created accounts and sporadically tell the world what's on their mind (or other bits) in 140 characters or less.
