This reflects particularly well on Yvain, Robin and Michael, all of whom managed to be both prolific and reliable in providing value with their quotes. I'm trying to think of a suitable metric by which I can formalise my intuitive evaluation.

I consider quotes with 0 votes to be a net negative contribution and it also raises the chance that other quotes by the poster are faux-wisdom. That is, that they appear deep at first glance for a casual reader but wouldn't stand up to scrutiny by someone who is paying close attention to actual meaning. That is, I would rate the comments that are posted via an 'accuracy by volume' approach as even worse than the average suggests because it signals a greater degree of superficiality bias.

Above considerations aside volume does provide some degree of increased value. In considering the question "Which contributor's page should I read in order to absorb the greatest improvement in quotey wisdom?" i may be better off with "16 in 5" than "22 in 2". On the other hand reading a "5 in 50" page may make me net sillier as I unconsciously absorb nonsense. Perhaps the ranking I'm looking for could be something as trivial as "Sum - Count * 4".

If I were to venture a suggestion: statistical significance may be relevant to your valuation of high-average high-number posters like Yvain, MichaelGR, and myself over higher-average low-number posters like michaelkeenan. If poorly-selected quotes nevertheless have a small but significant probability of being highly ranked (but a simultaneous large probability of being low-ranked) and most quoters select poorly, someone with only one high-rated quote is not much likelier to be a good selector of quotes than not. In contrast, someone with many quotes, most of which are highly regarded, could be expected to be unusually discerning, as the probability of this result by chance is low.
