Generally a pro-development forum, yes.
There are a few over-zealous/ridiculous height-at-all-costs people, and there are a few elite-ish "I am trying really hard to seem unexcited by the prospects of Boston's skyline" people. But most of us fall toward what one might call the "restrained YIMBY who appreciates design quality and good planning" spot on the spectrum.
Meanwhile, let's face it, it is only human for self interests to govern our opinions on specific projects. I hate it, but it is what it is. You cannot tell me that half or more of the "friends of the _____" community group people (I am talking outside this forum) do not have a financial stake (ostensibly negative) driving their activism toward projects. I mean - I get it - if someone were to propose a crack rehab facility in front of my condo that also happened to block my view and also happened to have a green line train storage depot built in, I would come up with reasons to protest the project even if it were in the greater benefit of 99% of the rest of boston. I am just tired of the two-facedness of it....people should just say "this project screws me". Instead they make up BS reasons about the design, aesthetics, flowers, bumblebee pollination, shadows, squirrel population, transportation, wind, and, can't forget: cars.
