I honestly don’t think this will have any effect in a potential employers decision to hire you. It is unfortunate to hear those things though, but you have to remember, as JBaldwin said, people have a tendency to do and say stupid things due to the anonymity provided by the internet. You know the quality of your work, that’s what matters most. Typically when people post insulting comments it is because they themselves are hurting, or are probably jealous of the skills you possess. The best thing you can do is to ignore them, their aim is to get a reaction out of you and make an impact with their provocative comments. If you don’t give them that satisfaction, then they’re just wasting their time. =)
