ZDNet highlights 10 grammar mistakes to avoid because, frankly (they’re just being honest because we’re all friends), they make you look stupid.

While we at Lifehacker have certainly NEVER made any grammatical slip-ups in the course of our daily posts (right?), ZDNet does highlight several very common mistakes that we’ve all made at one time or another. Personally, I’ve never been a big fan of people who get too up-in-arms over a misplaced they’re/their/there (I’m a benefit-of-the-doubt kind of guy), but I do agree that its it’s important to avoid mistakes when you can.

What grammatical errors really stick in your craw? Let us know in the comments or at tips at lifehacker.com. — Adam Pash
