I'm really excited about this. I don't know how many times the intertubes have answered my coding questions. Very often the answer is worth a lot, but there hasn't been an easy way to give back.
This could be a good reason for both those looking for answers and those giving them to go to http://bug.gd
I'm less excited about this. Tipjoy only lets you gather your tips after you've gotten up past $5 in tips.
Now, since bug.gd mentioned $0.10 tips in their post, only the very very prolific (and very very helpful) bug solution poster will ever have a chance of cashing in (and then only for an Amazon gift card). Everyone else will just have 0 to 50 cents lying around taunting them.
I understand why tipjoy does it the way they do - intrinsic micropayment issues and such. It just doesn't seem like a good way to get money to anyone but the popular bloggers/internet personalities.
Of course, I could be wrong. Maybe people like leaving $10 tips for bug help...
The tip amount is up to the tipper. The default is $0.10, but you can set it up to $0.50. After you tip, there is a link to give more, where you can give quite a lot. You can change your tip amount here: http://tipjoy.com/settings/
So an active user of their site probably won't have to worry about accumulating enough to reach $5.
