It seems to me that a big factor in this is just password fatigue. We have so many password "protecting" things from the very important like bank accounts and company data to trivial things like this forum, frankly, and other such stuff.
Frankly just about the only reason to have a unique password at a site like this one, is so that it's not reused elsewhere where the password is important. That way if this site has bad practices or a disgruntled employee, nothing important is compromised.
I wish this site used OpenID so that there'd be one less site to remember.
