Why do so many people care about punctuation and grammer for forum post?? These aren't essays... they are supposed to be free flowing conversations. But if you have a post that isn't pretty much edited by your college english professor people always troll the heck out of you. This coming from people that use twitter and text where its basicially pigeon english?? I just don't get it.
Some people do not necessarily find Twitter or text abbreviations acceptable, either. And these are supposed to be free-form conversations in English. Some people find it offensive or confusing when a post is beyond all saving. If I can't understand the point you are trying to make because of incorrect English, it makes the forum less effective.
Plus, sometimes I put it in there just so maybe I can be the person to help someone understand the difference between 'there', 'their', and 'they're'. I know it's unlikely if they've come this far, but it can be pointed out with kind intentions of helping someone improve their English. It's not all "you forgot an apostrophe, you must be an idiot".
