Dear fat,<p>This post comes off to me as cocky and untrue.<p>First, the general tone of this seems very pompous to me. To me, it reads: "I know so much that even building the most popular project on github and possibly of any library on the web can't teach me anything new." It might have been a little more gracious perhaps to thank people for using and contributing to the project...?<p>Also, you definitely learned something building bootstrap. I'm willing to bet you learned a lot of things between the few major version updates and 2,500+ issues, most of which are closed. In fact, here's a presentation that <i>you made</i> detailing something you learned from bootstrap (accessibility, specifically): <a href="http://wordsbyf.at/2012/05/21/jsconf-argentina-2012/" rel="nofollow">http://wordsbyf.at/2012/05/21/jsconf-argentina-2012/</a><p>I'm really not trying to be that negative guy on hacker news, this was just my immediate reaction upon reading the post. That being said, congrats on building an immensely popular and important library, and here's to hoping that you learn and always continue learning.
