I mostly work on PHP/MySQL with some frontend so, to diversify my skills - I want to spend some time learning Android application development and release at least one app in the Android Market. Not very sure about the app itself; may be something like sending my phone's sensor data to a web server using REST API.
craigslist is of course a great place. I've gotten many jobs there over the years. In reference to the op though, in terms of resumes I've been pleasantly surprised at how good LinkedIn has been working out in my current search.
