Now personally I'd rather be able to tell jokes on HN than be able to veto. But then again I'd have to sift through the bad jokes that other's tell.
In any community like this it takes some time to learn the rules. I'm sure there are quite a few people who don't necessarily know who "pg" is for that matter.
And now I went and explained it. Sorry, tptacek.
If I am selling something and asking $1000 and the person comes back with an offer of $500 and assuming I am willing to take that offer (because I was shooting high) I need to offer some "kickback". This could be as simple as saying something like "well, if I accept can you pay within 5 days?" Or perhaps, "can't do $500 but I'll consider $600". Otherwise the buyer feels perhaps "hmm wow that was to quick and to easy" and might back out of the deal. Strictly my experience over many years.
Instead you should ask to be able to green-light one applicant per batch. That way, it would be possible for your contribution to be very valuable.
