But... your example URL makes it pretty easy to guess at other people's mixes... so not very private. Not that you claim it to be private. But if I was sending a mix to someone and typed in a special message for them, I would not really want random people to read it. Some sort of URL hash would at least make it harder to guess.
Good point about the mixes, I may change that in the future but this isn't looking like it's gonna be a long term project so there might be marginal return on the time invested. Thanks for the feedback!
Second question: i like the design given the time constraints. What design tools did you use? Any tips on getting a good design quickly?
2. Thanks! I've been really concentrating on my design skills recently. Biggest tip to get good quickly: copy other designs and do it a lot. The design for this site leans heavily on the Instagram homepage. You just need to find another site that captures the feeling you're trying to create with your product and then put your own spin on it. Also looking up how books are laid out especially Renaissaincs era layouts that use the Golden Ratio like the Van der Graaf canon are very helpful. Email me I'd be glad to Skype some time.
There's no magic bullet. Everything's hard at first. But if you do it enough it gets easier.
Without the example starting me dead in the face I would've lost interest. I only clicked around because this was on HN and I wanted to explore so I could give constructive feedback.
