It seems like there are a lot of stats about the geocaching teams, but I'd
be interested in seeing more about the caches themselves.

How about average finds per month for each cache or a graph of finds per
month?

The travelers are becoming more popular.  Maybe if Snaptek counted the
number of travelers picked up by a team or the average time a team kept a
traveler, the travelers would become more popular.

Anyone have any other ideas?

Thanks,
