if such nudges might effectively save some of what's being lost, i'd be all for it.
allston does still have some of what made kenmore and harvard fun (as does central), but in both cases there's ever-encroaching development that's eroding at the fabric of what makes those areas interesting -- not just to young people, but artistic folks of all ages, and to any who would rather eat at a random ethiopian restaurant than a chipotle (or whatever analogy works for you).
with two condo developments in the works, i have it on very good authority that o'brien's will be gone in a matter of years (hopefully later, rather than sooner), denby rehearsal space is gone, as is all the artist space on rugg road, galaxy park studios had to move to the north shore. over in central, condo development booted new alliance, wemf, and a ton of rehearsal and studio space. and so on and so on.
heck, over in charlestown they're trying to convert the CRS rehearsal/art studios -- one of only two sizable such spaces -- into condos.
i know stuff changes and that's normal and fine (plenty of my musician/artist friends have the same complaints about the village, brooklyn, and LES, so i get that it's not exclusive to boston), but when you make it so that everything and everyone quirky and creative has to LEAVE the city in order to do what they do then a lot of the unique appeal of an area leaves, as well.
anyway... back on topic: this new building sucks donkey dick.
