Anon for this. I'm sitting on some cash - I'm not sure buying a condo, some index funds for retirement, or some such "sensible" thing is really my temperament. I'm far more tempted to try some angel investment. Ideally I'd start my own company but I'm a couple of years away from a greencard (will probably be 2 more years and I'll be 35 and ready for a mid-life crisis :*).
I've been here a little while working in large semiconductor companies as a compiler/systems software/architecture guy. But, I'd rather invest in some small groups which are not in such a capital intensive.
I don't have the extensive network of contacts, startup experience or cash that yc has, but perhaps hackers here can suggest a way to dip a toe in the water?
