It is so often said "your github account can be a great resume", but what does that really mean? What will a potentional employer specifically look at on your github account? Will they glance at the most recent project you committed to and assume this reflects the majority of your work? What if you have forks of projects that you have not actually committed any pull requests to at all?
If you were an employer, what would you look at on a github account?
Accounts that are just vimfiles and the skeleton of a never-again-touched project are boring. Forked repos are neat, because they show what you're interested in and what you've been exposed to. Forked repos that you've contributed to are even better. Your own projects that others have filed issues and pull requests on is the motherlode; that tells me a ton about how you do the job I'm hiring for.
