To remove Blinkfeed go to settings>personlize>homescreen. You can turn it off there.
Opps, I guess that doesn't work. I had seen it before and just looking at it one would assume that turns it off. I had never tried it though. Decided I should see. Doesn't seem to though. Pressing on it just returns you to the homescreen and Blinkfeed is still there. Rebooting didn't help either. Egg on my face I guess.

You need to do as runandhide05 said but when the menu pops up, select manage homescreens. Then slide things so you can see the Blinkfeed page. Then click the remove button at the bottom.
