maybe 当局者迷，旁观者清? all they are doing is telling you what they, as strangers, see and feel when they visit your site/service. you can choose to accept those perspectives or not. and some of the feedback is even actionable. and if even that is not helpful/useful i cant really imagine what is, especially considering you asked some strangers for help and they all have nothing to gain by either helping or not..they're all just..trying to be helpful?
