The kickstarter page isn't quite up to snuff to really get this off the ground. The project looks great, but the kickstarter page is going to prevent a lot of people outside of hubski from backing a project they would probably already love.
You really need to show people why they would use this versus testing, and what donating more money would get for everyone. Show me some stretch goals. Hell I donated 1000$ to homestuck so I could get in the game credits.
Offer actual cans sent to people's houses if they donate something like 50 dollars. That's a neat dumb trophy that says "yo I made a contribution." for something like 20 dollars offer sheets of hubski stickers. Stretch goals should have some similar aspects.
So let's say at 2500, you guys get a graphic designer to help with the ui. At 5000 you give everyone who contributed the "pro" version; that's a great way to get people using your product and contributing. Give people who contributed specially colored names or something can also work, but that does have some downsides.
One of your later goals should also be making tincan open source. You might be tempted to right now, but while that's a noble effort, its much more effective to make people strive to get it to open source. Your primary market is going to be redditors and younger people, and a large form of activism today is spending money on helping small developers.
I'd also recommend using your real names, not your hubski ids. Yes, it makes it less anonymous, but if people are paying you for something, they want to know they can trust you, and showing names means trust.
The product itself looks cool, but kickstarter is essentially a marketing platform, and you need to convince people why they would pay a premium price for a product that's going to go anywhere from 2 dollars to free.
This seems like a lot of criticism, but its really not. The idea is great, its the pitch that needs work. I'm actually ready to pop 100$ on this, but I'm only doing that if I know it'll succeed. It totally can, no pun intended. Just show me.
