The one point about Cyber friendships that makes them different from other types of direct contact friendships is that you get to know a person from the inside out. This isn't necessarily a good thing. However, eventually, I think you can usually get some idea of a person's character from their general manner of posting. Unpleasant people pretending to be something they are not, will usually show their true nature sooner or later. I have seen it happen in my case, where I have observed something in a post that has made me change my opinion of someone completely. Could be anything, maybe inappropriate language, a snide remark, or something that shows a lack of integrity. I know, deep down, that that sort of person is not someone I would normally choose as a friend. I just phase them out at that point.
As for not knowing what we look like, a visit to No Mercy's picture gallery at http://188.8.131.52/pcpitstop/page1.htm should help. By the way, we could do with a few more photos up there. (Hint to Volt )
