Devstats is a website for developers looking for statistics on languages, frameworks and tools. The main focus in mind when developing this was the Job seeking information that would be useful. As a new graduate myself, this data could come in handy with knowing what technologies to learn next.
Another good example of this website's use would be for those looking to relocate. They are able to see what tools are used in an area prior to relocation. This could allow for easier preparation on what to expect.
