Inside Higher Ed has chronicled a kerfuffle in the English Professoriate with regard to live blogging or tweeting conferences. The debate began when @eetempleton tweeted "It's presumptive to assume that we should share other people's work w/o asking"
Did I mention this was at a conference?
This touched off a conversation (lamely called "twittergate". Can we stop adding "gate" to stupid shit please? Seriously, these are ENGLISH profs and that's what they came up with? FFS.) that had me holding my sides.
Maybe conferences in English are different from science ones, but when I present something I want as MUCH EXPOSURE AS I CAN GET. Is there anyone out there presenting lab secrets at conferences, hoping for a small audience? WTF?
But here's the problem: You can't control what people write on the internet. Did they regulate phones and personal conversations in this field prior to Twitter? Sorry English profs, but welcome to the 21st century. It turns out that there is still the freedom to write what you want on the internet.
Instead of fearing that someone outside of your direct "in room" audience is going to hear what you have to say, embrace it. I consider it both fun and a bit flattering when someone bothers to post something about a talk I gave. It means that people are actually interested in what you have to say. If you're worried about the Scooping Boogeyman, then tailor your talk accordingly. But unless your goal is to have the smallest impact possible, you would have to have you head up your posterior to fear people actually discussing your work with as wide an audience as possible.
