Medvedev "follows" the White House and Obama, and only?

Right now , Medvedev ’s “following” list looks like this:

whitehouse @BarackObama @KremlinRussia_E] "/>

Perhaps I have played for too long in MUD, where the word “follow” and its derivatives have a more literal meaning than on Twitter ... but it’s somehow uncomfortable for me to look at this list .

I am sure that I would treat this completely differently when and if this list were wider and included (besides Medvedev) not only @ whitehouse yes @ BarackObama . However, for example, Jobs in the list, on the contrary, no. Why is this so?

_{Obama , by the way, has the opposite situation: “722,941 Following”. Also uncomfortable to see such things. Obviously, he does not read them.}
