Below is a list of official public forums run by web hosts (contact me if I'm missing one). Check out the forums for yourself and see which employees post, determine their technical competency, how they solve problems, how they treat customers, etc.
This method worked for me back in 1996 when I found BEST.COM (now Verio) by reading the exploits of BEST's Matt Dillon in the ba.internet newsgroup. Now 9 years later, I'm resuming the search and sharing my methods.
Good luck to us all,
