By the way- for security issues, their security@valvesoftware.com address gets /very/ fast, human replies. For example- when Steam Curators rolled out, you could use javascript: URIs for links to "read full review". 5 minutes after Curators was released to the public, I discovered that. 30 minutes later, it was fixed.

That said, that's just their web app; getting issues fixed in games is MUCH slower.
