Ask HN: What is Boston hacking on?

Hey all,

My name is Kevin McCarthy and I'm a writer at BostInnovation.com, a Boston-based publication. I focus on tech and web/mobile development (see here: http://bostinnovation.com/tag/programming/).

I'm curious: what is Boston hacking on? If you'd like, post a comment on this to let me know. Hopefully, I'll be constructing a view pieces on the responses.

Thanks everyone!
