This was what I got when executed cat /etc/hosts. It's the same as yours up to the part where it reveals the fact that I'm a dirty cheapskate and have an unregistered Adobe program on my computer. If that's the cause of all the delays, I think I'll have to live with it. Another pass by EntreCheck is pasted below that.
