It's just for fun. It's much the same as if you vote my answer up 100 times and I get a badge. If you could do that, I'll let you know if that or the gold star gives more virtual satisfaction.
The advantage is more for githubGitHub, it's a very clever way of reducing support requests down to the absolute minimum text. If the same were applied to answers on this site, I'd not have added the attempt at humour which adds nothing to my answer.
