I wrote a program which travels Battle.net channels and examines user's statstrings to find clan channels, then it visits them regularly and averages out certain information each visit. After about 3 hours, it collected over 400 Azeroth clan channels (I never fed it any, it started off scanning the "available channels" which Battle.net sends you).
This could help gamers find clans which are of their skill level, or active clan channels which are worth visiting.
Revision 1 of the table is available here:

In the future there'll be sorting methods. Currently, I'm manually uploading the ClanList.html file which the bot generates, so I might not upload the next list until the bot finds another hundred clans or so.
