Some social sites, such as Facebook, don't give you any inkling of when your profile page, or any materials you post, have been viewed. Some dating sites let you know how often your profile has been viewed, although one can never be sure whether this is an accurate figure or an attempt to get people to upgrade their accounts. Academia.edu lets you know when someone visits your profile there from a search and the keywords they used to find you.
Personally, I really like this feature of Academia.edu. It is always interesting to see that when details of a conference session I am presenting at is posted up online, I get a surge of visitors - even if the small check I have done indicates that maybe this counts against attendance. One conference workshop, I asked whether any of the people in my session had been amongst the ones who had searched and found me on Academia.edu, and nobody there admitted to it. I deduce that the people who had looked me up had decided not to come to the session, but at least that meant that they didn't 'waste their time' coming to something they presumably decided they were not interested in!
As part of the This Is Me project, I interviewed a number of students. One of the questions I asked was whether they thought it would be beneficial, in terms of managing their Digital Identity, if systems like Facebook let them know when their profile had been visited, and possibly who had visited it. They unanimously said that if they knew Facebook did such a thing, they would be less likely to use it, despite all saying that they never browsed around other users' pages much.
Maybe I am just out of step with the younger netizens, but it seems to me that having this sort of information is really useful. If you are nervous about being stalked, this information might give you a heads up if something was going on. If you are building your Digital Identity to help promote yourself, either for your career or just your general social profile, it lets you know how you are being found.
