His security blog at Facebook: "Facebook Security: Fighting the Good Fight" <a href="https://www.facebook.com/blog/blog.php?post=25844207130" rel="nofollow">https://www.facebook.com/blog/blog.php?post=25844207130</a><p>edit: here's the obligatory "but this is blogspam" note...Kelly's employment with the NSA was first reported by the the Times here a few days ago (<a href="http://www.nytimes.com/2013/06/20/technology/silicon-valley-and-spy-agency-bound-by-strengthening-web.html?_r=2&" rel="nofollow">http://www.nytimes.com/2013/06/20/technology/silicon-valley-...</a>)...but yeah, here's a classic case of newspaperism vs. sexy-SEO-headlines...I didn't read "Web's Reach Binds N.S.A. and Silicon Valley Leaders" because it sounded no different than other recent stories...but a Facebook exec going to work for N.S.A. is definitely a headline-worthy fact.<p>However, Kelly isn't the stereotypical young Bay Area millionaire ex-Facebooker...he previously worked as an FBI analyst before joining Facebook (<a href="https://twitter.com/wrox/status/1699420309" rel="nofollow">https://twitter.com/wrox/status/1699420309</a>)...So going from FBI to Facebook to NSA isn't as strange as, well, going from college to Facebook to NSA, unless the catered lunch at NSA is classified and delicious. Not knowing why he left Facebook...but after doing so, it's not out of left field to go back into federal security, especially if he had a NDA with Facebook not to go to other competing services, such as Google.
