I look at those numbers constantly!
If someone criticizes the coords, I want to know if it's a newbie. I'm interested to see someone with very high numbers hit town. I'm interested to watch the progress of familiar names in my area and see someone who started after I did blow past my numbers. It tickles me when somebody makes a rookie mistake and they've got a respectable find count. It tickles me when a rookie breezes through one that gave me a really hard time. I could look up the numbers of everyone who logs, but I probably wouldn't bother.
And, of course, I particularly like my find number. I don't have a high count and never will at the rate I go, but that just makes incrementing that number more significant. The logging ritual is important to me. I do log my finds in order, and after I log I look at the cache page to see my log in context and my name with that one-cache-higher number on it. And I think, "woohoo! Who's the weasel? I'm the weasel!"
If performance would be significantly improved without that number...eh, even then. Nudging that number up one sadistic multicache at a time is a big part of the pleasure I get out of GC.com.
Exactly what Auntie Weasel says here (well, except for the "woohoo! Who's the weasel! I'm the weasel!" part). I look at the numbers all the time, too, and for the same reasons.
So I'd also like to say please don't remove the counts from the cache page.
