Thanks, mcintyre1994! We're using Susy and Compass for responsive CSS. We have plans for an Android version, as soon as jpn learns Java. :)
Great feedback on our home page -- you're right about the iOS emphasis, and limited content feel. We're currently refreshing our home page, and will be sure to work these issues out. Thanks!!
Thanks all for the kind words of support! Another essential resource was Basecamp's (formerly 37Signals) book, Getting Real. It is a must-read for anyone building software, especially for first-timers like us.
I've been traveling for the past two years, and fortunately have only had positive experiences with Airbnb. I agree that some hosts can be less responsive others, so I've taken more time on my end to have a bit of back-and-forth with the right ones before booking.
Paul does make a good point regarding host cancellations, and your suggestion to publicly display acceptance or cancellation rates might be helpful to prospective guests.
Though I share your sentiments about losing the 37Signals name, their philsophy remains the same and I have high hopes that this change will result in an even better Basecamp!
