Or just ask them to invite some people man, don't stress.
I invite people to events almost every time I go out and talk to people.
Well there's the first issue. That's harder and harder to do in this economy, and the quality of people I meet aren't exactly the ones who won't flake 80% of invites.
In 15 years of throwing banger parties it was by far and away the most absurdly over the top, yet somehow also the most wholesome, party I've ever thrown. Actually I'm not sure why I haven't done it again now that I think about it. And the ratio of girls to boys + enbies was like, 5:1, absolutely ridiculous.
Anyway you could try it?
Another time I threw a party on Meetup.com and had a bunch of old people show up, who ended up getting turnt the fuck up. I made a lot of good software industries connections that night and it was early in my career so that was very useful as well.
