Thought I would start one up for Fletcher, since fair amount of people have already been admitted and are probably thinking a good deal about the pros and cons (as I am).
Pros:
-Any academic within IR will probably tell you that Georgetown SFS and Fletcher are the best IR schools, because they focus exclusively on IR, but are still comprehensive within that field (I think SAIS loses a few points there for being so econ-focused)
-Great atmosphere, students seem to love it there and have a true sense of community (when I visited they had all come back from a giant group ski trip)
-Great network, Fletcher alumni are everywhere and really eager to help grads
-Very flexible, you can really build your own education based on your interests and preferences
Cons:
-People will be angry with me for saying this, but my biggest reservation would be that Fletcher has a "brand" crisis. Once you move beyond IR academics and people who are really in the know about IR schools, Fletcher simply does not have the same name recognition as other schools. I know this from my own experience since I was accepted in December and have since received a lot of blank stares when telling people I was thinking of going there. And this was not just with my family and friends, but also with people in DC who work in IR as well as everyone I've spoken to abroad. This lack of recognition is really undeserved, but it could influence my decision as I want to have people look at my resume and automatically respect and recognize my credentials.
-Location. Basically, its not in DC or NYC.
-Tufts campus/Medford area are nothing special.
