Shut your hole unless you have been there, done that

I remember talking to Seth Godin a couple years ago and he told me the reason he doesn't allow comments on his blog or on Twitter/Facebook is that he can't handle anonymous criticism. He went on to talk about how he wishes everyone had to present an ID of sorts to make a comment online. Now I have always embraced feedback...

HOWEVER

When I see people on FB/Twitter/Comments Section make remarks about how I am "failing", or "missing revenue because I am not doing X", Or as what just happened recently: some guy just made a post talking about people that have popups on their website. Of course he has ZERO quantified data, though. Here is what I do... when I surf around the internet and see something that I would do different BASED ON MY EXPERIENCE I will simply share with the person something like, "Hey I see you're doing X. With X company/site I did X like this and saw a big result. Just wanted to share that with you" Quantified results. Take from it what you will.
