How much do/would you donate/crowdfund and to what kind of projects?

[universe_]

I generally go with less than 0.001 for most projects unless I know their ins and outs.

Being on bitcointalk for 1.5 years has made me a bit paranoid.

No kidding. With even some of the more trusted ended up scamming there's no way people wouldn't take precautions.

it is too small amount to test something out, in my opinion you should go at least with 0.1 as it is not too much and thats what i usually invest
