I did my grad work up here. I then recruited from schools up here (still do). And now my kids are heading into the post-secondary school selection process after I've lived here for nearly 30 years. I'm quite sure I know the area, in terms of how schools are viewed.
I was quite clear to frame the commentary in a comparative manner ... there's a pecking order amongst the many schools up here. And, yes, BU and BC are seen by Harvard and MIT folks as "also-rans." They're quality schools, for sure (like Tufts), but Harvard and MIT are the elite, and BU, BC and Tufts are in that next tier (I just looked it up to be sure - BC is T37th, Tufts T37th and BU is T41st in the latest US News rankings; whereas MIT is 2nd and Harvard is 3rd). Even Brown (T13th), which is nearby, gets snickers from Harvard folks as one of the "lesser Ivies," even though it's obviously a great school.
This isn't controversial ... not sure why the personal shot over something that's not at issue. I could say our Sun is a star and some fruit loop would disagree and take a personal shot at me. And, inevitably, bison would like that comment.
