I've solved some coding challenges I come across, but mostly because I wanted a little diversion. Generally those problems give me an excuse to practice lesser used languages or languages I want to learn. I've been contacted by companies after solving these, but I always decline.

In regard to the change in hiring practices, "social presence resumes" are just a passing trend. It may result in better candidates in the short term, but people will learn to pad these new resumes and it won't be much more effective than paper resumes.

The best hiring practice will still be tapping your employees' social network and hunting down talented people who aren't happy in their current positions. Anything else is usually a shot in the dark.
