Three things I hate seeing most on the internet:

1. People who literally beg for thumbs up (youtube) or likes (facebook)..., I'm not sure I'll ever understand this need for fictional attention and approval..., write something meaningful and you just might end up getting a thumbs up.

2. tha best game eva, this is so kewl, friends 4 life..., poor examples but you get the gist of it, I hope.

3. Those who use LOL, ROFL, and bunch of smileys even though often enough there's nothing to laugh at in their post.

How bout you? What grinds your gears on internet?
