I think you have a point if you locate problems with campaign platforms on a candidate's web site.
On a message board, I totally disagree. Message boards are like a conversation. In a verbal conversation, most people say things that they'd never write in a serious paper (mostly, sentence structure, or use of words that are better in a conversation than in a serious paper).
In addition, I always try to remember that a lot of people access this board, and post on this board, from their SmartPhone. I frequently make mistakes when I text someone, or try to post on this site from my phone. It doesn't mean that I don't pay attention to detail. It simply means that my fingers have never been crazy with keying in things on SmartPhones, and with autocorrect "fixing" everything, I don't even notice a mistake before I send it/post it, unless I take time to review what I've keyed in before sending/posting, and I don't always have the time to do that when I'm on my phone.
