I can't tell from the site design whether Doctype is created by the same team as Stack Overflow.
It doesn't seem to be, as it doesn't have support for OpenID like the other sites (i.e. Server Fault and Super User).
So, is Doctype part of the same family of sites as Stack Overflow?
If not, is there a similar site for web designers created by the Stack Overflow guys that gets the same kind of traffic?
