You request lacks the most important aspect: you!

How can "we" give you advice if we don't know what you like and what you enjoy? Socializing is about sharing and exploring - and you want to do something that suits your personality and your interests.

So instead of bending over and trying to do "something" social just to meet people will feel awkward for you and your fellow socialites.

First ask yourself if there are any less geeky things you enjoy or would love to explore? Then dive into these things. If you have fun and a passion for something it's easier to socialize and find new people.

Don't try stuff you simply dislike to meet the ladies - they will smell your awkwardness instantly.

If you find yourself too geeky or unable to find any non-geek topics then join a social, environmental or political cause with your full geek powers and throw yourself in. To volunteer for something is a great way to meet people and the ladies - and you might enjoy your own geekiness and doing something "good" while socializing ... (just make sure not to confuse socializing with fixing everybodies computers).

If you like animals then get a dog - I hardly know any better "tool" (apart from babies) to make the ladies go "Uhhh" and "Ahhh" ... and talk to you.

Steam is terrible and you can't sell your old games bought via that dreadful system.

And I still have my old QuakeIII CD ... somewhere ...

May I recommend reading my essay about Digital Penis?
