Although there are many (too many) times I cringe while reading something poorly written on the Internet, I try to make it a policy not to pick too much on specific people or sites. The one exception is people who profess themselves as writing experts but who make awful, repeat mistakes.

A classic case of why people shouldn’t harp too much on other people’s mistakes. (Maybe we can blame it on a case of auto correct gone wild.)
