These are general comments, not directed at anyone in particular.
(Okay, I'm lying. Check out my shifty eyes.)
My reference, as always, is Oakland, which has Jack London Square (JLS). It has been an erratic venture, for its intended purpose and, ultimately, a failure, forty years on, as a commercial venture.
'They' continue to reinvent it. Well, good for them. Who knows what mix will make it 'right.' The locals go. The tourists don't. The locals get pushed out. The tourists still scoff at it. The tourists are forced into it (don't ask; just trust me), and the locals think, 'oh, there's something better there now; let's go back.' Then the tourists ... ummmmm ... Hold it. Oakland has tourists?! Oh, right. They ship them over from SF or they make a stop here en route to a Napa Wine Tour because Oakland International Airport is 'the gateway to Wine Country.' (Brilliant marketing campaign, btw.)
Anyway, what has JLS become--primarily chains. Yet, even some of those chains have pulled out. Or were forced out by the management who wanted to alter their vision again. (The details remain sketchy.)
What Oakland wants IS a touristed-version of a small, convention-attracting, entertainment zone where the locals and tourists alike can intermingle in a controlled setting that doesn't threaten or challenge any of them too much. (Which JLS was before the management and the paranoid city leaders messed it up some more.)
What have they (well, I) learned from all this?
There is NO magic formula! (I knew that.)
(This goes for much of anything that humans like to believe they can control.)
No, I will not apologize to the branders/marketing trolls/demographic junkies who inhabit this forum. Sometimes ideas work; sometimes they don't. Sometimes in the same place, simultaneously. Sometimes in one place and not the other. Crunch all the numbers you want. Meaningless.
Simply, somebody had a vision. It wasn't fulfilled. The vision got muddled. The 'visionaries' got lazy. The management sucked. (Easiest explanation of all.) Who knows?
So, back on point--Boston's Seaport District? Chains, mom-and-pop, locals, yokels, rentals, condos, monied, poor, artists with or without trust funds--bring on the cranes and let the developers have their way. They'll be fiddling with their best laid plans for decades after we are gone, trying to figure out why x worked and y didn't even though they both should have complimented each other. Meanwhile, Ellard from Ellington in town for the E-ware convention will probably opt for the Appleby's in the lobby of the yet unbuilt, but sure to appear, MoPo-Hotel 6--the first mid-rise, modular, pod (capsule) hotel of its kind in the US. And everyone will come, locals and tourists alike, because everyone will want to try it out, until they build them elsewhere. Then the Seaport will have to invent or discover some other fleeting, novel attraction to entice some industry's convention planner to book something there.
Edit: This is also a relevant rant for the BCEC expansion thread.
