working at a startup :(
Perhaps what you meant was "Working on my startup." To which I would agree. If I could be doing anything right now it would be working on my own projects and working towards being able to sustain myself through the application of my own skills. Perhaps that's not what you meant, but heed my warning, startups are not a panacea for programmers.
I do play around with new languages/libs/tools/etc. though.
