TL;DR I'm not against renaming it, if there's a solid reason for doing so.
First, I think it'd be a good idea to explain what the goal of changing the name would be.
Some things to think about:
- What kind of people do you want to make up the core membership, which will define the culture of the space?
- Changing names at this point is throwing away hard-earned brand name recognition.
- People (as in, the general public) are generally intrigued by "hackers". People like what they've seen in movies and TV shows about hackers (and it's not ALL inaccurate).
Keep in mind that I don't live in NYC, so perhaps I have a different perspective; and I am a supporter, not a founding member, so I inherently have less of a stake in hackert0wn.
