I was interested in your take on those who look at your profile and don't correspond. I notice plenty of them looking at my profile but I don't have the same perception of them being voyeuristic or creepy. There are many who do correspond so my upcoming comments do not refer to these people.
Those who don't respond, either to my profile or to my posts are still participating in their own way and this I respect as their choice. There is a sense in which all these sites have an entertainment element inbuilt into their structure - in a similar way to people getting used to sitting and watching the TV screen, with necessarily commuicating wth those who are doing the entertaining. ( Although there are many who will shout at the screen as if they are talking to someone live! -- I'm like that watching the Rugby!)
When someone looks at my profile, my reaction is one of mild satistfaction and appreciation becasue I view it as an indication that they are interested enough to learn a little more about me. Not that the profile tells them very much more than the posts.
Sometimes I return the gesture and look at their profile, so that I have a better idea of who takes that little more interest but on occasions I too decide not to follow through with correspondence on the issue of who is looking at my profile becasue it might prove to be more than they inquirer wants.
Just some thoughts on the subject
