ysabelle - that could be a good sign. During last year's R3, I had a linkedin view from "Director of Admissions" at another program. I was eventually waitlisted and then denied, so it certainly doesn't guarantee good news, but it's extremely likely that more schools look at peoples profiles all around the web (facebook, twitter, etc as well). Also, whenever I get someone with those privacy settings it tells me "from the greater ________ area" which indeed includes the city itself. I wouldn't read into the difference between that and just Boston or Cambridge.
Anywho, just wanted to throw in my 2 cents
