The poster is right. Next up, I'm expecting another whiny thread about why all these t-shirt wearing "fuck that shit" guys aren't paid or treated like doctors, lawyers or architects. These are _public_ presentations. Act professional. There are almost no other professions where it would be considered de rigueur to pepper your professional presentations with profanity, or, for that matter, porn. You want to swear in your office, or in your source base (not in the public-facing API stuff), go ahead. But if you want to swear in your public persona as a professional, don't expect to be treated like that much of a professional.
