My thing's a bit like airbnb but where you can buy the place if you like it. Fairly confident I'm not getting an interview this time round - no views on my vid. I don't fit the YC pattern very well.
I honestly wouldn't worry about it.
Anecdotally, I'd say >50% of our batch applied more than once. The one thing we all had in common was traction/progress between applications. This is probably the single best thing you can do to increase your prospects of getting in, as it shows YC that you are 1)serious about working on this, and 2) capable of doing what you say you're going to do (which is to say, make something people want).
Happy to also provide advice that's tailored specifically to what you're building. You can reach me at (firstname @ lawnlove.com)
Go get 'em!
If someone's interested in getting involved drop me an email 0707tim at gmail. I'm in London now and may be in LA/SF shortly. One of my problems applying to YC is I'm solo presently.
