I noticed a very peculiar phenomenon on the web related to "loosing the face": something like a "collective trustiness". The internet is a big space to create trustiness. Whenever you post a note, a reply or a request in a forum, in an online auction such as eBay, in a dating place like meetic.com etc., people can prove your reliability and rate it. Post after post, request after request, you become trustworthy or loose your credibility.
This means that making mistakes it is not bad for itself (i.e. I don't know the answer to some specific question) but in relation to what you provoke to the others (i.e. in an online auction, if you sell something damaged, the buyer will give you a bad rate and next time you try to sell something else, the next potential clients won't trust you).
Online you loose your face if you lie and not if, accidentally, you make a mistake.
I hope it doesn't apply to me when you see this picture!
