WoW and "The Warden"

[I_Broke_My_MHZ]

I was considering getting WoW, but I've been reading a few articles about "The Warden" lately that cite concerns over the program's activity. Most notebly is the reading and verifying of every window title that is opened. So I have two questions:

1) Does "The Warden" send potentially personal data over the internet?

2) Besides reading titles, is there anything else worth mentioning about it?

After a lot of digging I came across this site:
