Where have all the Hacker News old-timers gone?

Nostalgia ain't what it used to be.

Are MLB Games Getting Longer?

On July 29, 2010, I had a flight from Denver to Cincinnati.  About an hour before boarding, I went to ESPN’s website and found a new article by Bill Simmons, a.k.a The Sports Guy (@sportsguy33 on Twitter).  The basic premise of this article is that a core group of fans is losing interest in Red

From July 20-23, this year's use R! conference took place in Gaithersburg near Washington. I attended the conference as part of my holidays in the U.S. and had a good time there.
