I'm not talking about things which I can tell are just plain typos, but errors that they make over and over.
Like in the photo communities where people post nude pictures of themselves and someone replies: "Your pretty" -- can I fix that?
Can I go in when people write "should of" and tell them what they have done wrong?
"To" and "too" also get to me when used incorrectly.
I know that some people just don't care about their mistakes. And most just don't know any better. But how can we show the rest of the world that we have some education if we can't even write our own language out?
