Mr. Karp, who founded the blogging service Tumblr, talked in depth about why his service did not provide a mechanism for commenting on Tumblr sites. He said the absence of such a mechanism was intentional, to prevent nasty comments. He said comments on most sites mad people feel like second-class citizens. “It makes you feel like you have to speak in all caps,” Mr. Karp said.
He said that no one had really figured out how to conduct meaningful and pleasant conversations online, but that he wanted to try to solve that difficult problem.

![Math! It’s hard!
For some people it’s really hard. They remember taking pre-calculous in High School and… just, oh man, it all comes rushing back! The anxiety, the frustration. Dear God, it’s too much for a mere mortal to bare.
Other people are more, “Calm down! Sure it can be confusing, but it’s not wizardry.”
“Yes, it is,” the fearful cry. “People who are good at math must be wizards! “
But the thing is, math nerds aren’t, in fact, wizards. They’re just brave:
Using brain scans, [scientists at the University of Chicago] concluded that the mere thought of having to solve a math problem causes quasi-physical pain.
Medical XPress quoted Ian Lyons, a psychology graduate from the University of Chicago and a postdoctoral scholar at Western University in Ontario, Canada: “The brain activation does not happen during math performance, suggesting that it is not the math itself that hurts; rather the anticipation of math is painful.”
There is nothing to fear but the fear of math.](http://web.archive.org/web/20121113152913im_/http://25.media.tumblr.com/tumblr_mcvg1jaKIE1qlnszno1_500.png)
