For the most part right? I thought the argument myth #6, what you know matters more than who you know, was made pretty well. And we haven't really seen much of such advice. Usually a lot of us here, myself included, dislike the notion of networking bluntly for such purpose alone, but it certainly can be helpful in the long run.
What's as equally important to note is the young brain power in the area. Over 400k students in the city and its surrounding areas. Higher-education institutions like Harvard, M.I.T, Tufts, BC, BU, to name a few.
You can also find cheap places to live in many parts of Boston. Lower cost of living in Boston than say, in NYC.
If you really do need to get to NYC, you can vie for a train ride there (~200 miles).
