Dr AnnMaria DeMars, former judo world champion and hardcore statistics geek, who I've followed on twitter seemingly forever:

• DrAnnMaria: If you're following me hoping to hear about business, statistics or programming you want @annmariastat
• DrAnnMaria: I have two twitter accounts because most programmers don't care about conditioning for martial arts or matwork.
• DrAnnMaria: On the other hand, with all the sexual harassment problems at conferences #OSCON maybe those programmers ARE following me here on purpose
