They almost always use present tense which makes it seem like everything already exists. From the campaign:

"Located in New York City, Hackert0wn is an epicenter for innovation and education to advance green technology and sustainability."

NO IT'S NOT! It's an idea in 4 peoples' minds. It doesn't exist so you can't make claims about it like this.

Almost all of the photos they show are of related tech and have no bearing on this project. Do they actually have permission to use those photos? Some look like they're taken directly from product manufacturers and other copyright protected sources.

No wonder they're using indiegogo instead of Kickstarter. Kickstart would never let them get away with this.

Do they already own the land or something? It sounds like at least one of the partners already runs a hacker space so I assume they know what they're doing, but it sounds wildly implausible to me. The typos and errors on the page don't exactly inspire confidence either =P

Why do we need spaces specifically marketed to "hacking"? Hacking requires a computer, a table, a chair and electricity - just about any real estate fits those parameters.

On top of it 1.5 million through crowdsourcing for this sort of thing I have to doubt would come even close to cutting it for getting things off the ground. Syndication through real estate investors would probably give you a much better shot.

If you can't be bothered to have someone proofread your first sentence there is no way I'm even thinking about giving you money.
