Building a checker; WHAT SITES DO YOU WANT

RTFM
I have decided to start building a checker, it would be great if you guys could tell me what sites you would like to see in the checker. The checker will be a standalone application (built with c++). Anyone who provides a website that isn't already in the checker will get a shout out in the app & readme. I also don't have a name for the checker, logo, nothing. Any input/freebies is appreciated.
