One of the recent members of my team was from a bootcamp, she's been a real joy to work with and has mad some decent contributions. Bootcamps may serve their purpose but like with anything else YMMV.
As a person with HBP who actively monitors it, I can tell you this much. Sodium intake definitely affects my blood pressure. It goes like this, the higher my intake the shittier I feel. I'm not saying sodium is the main or only cause of HBP, it seems to affect some more then others, and there may be other underlining causes. But to call it a myth is downright ridiculous.
The community seems to be split. I lean towards separating code by features. Having Controllers, Directives, Services in one file as long as it relates to a particular feature. You can have separate files for shared features.
The ease of which it is to get started with Sublime Text may be a factor. It's nice not having to worry about managing plugins and custom settings. Though I see no reason to switch if you have taken the time to customize vim to your liking. Once you get a decent package management system for it (Pathongen, Vundle) it's hard to beat.
I've lived in Queens all my life (29yrs). This Spring was the first time I've stepped foot on Roosevelt Island, they have a decent indoor pool there that's pretty cheap.
