I don't think is a viable strategy for building a social life. Gym attracts asocial weirdos (not an insult, I happen to be one). I would consider getting a really hobby or switching jobs. There's a lot of turnover in the food service industry, plenty of chances to meet new people. If you're an unemployed CS grad what do you have to lose? The best thing though would be finding a romantic partner and just devoting yourself to that person, instead of moving from one fleeting friendship to another.
