Dude, take it easy. You are making yourself look like a fool. 2 posts just because of 1 user, that isn't going to help you.
Anyway, let's talk business. First of all the price for your website 50
BTC, way to much. You should be happy if someone paid you 1-2
BTC for it. It doesn't matter how much work you put into it, it is not worth 50
BTC. You might get that much if you get as many visitors as Blockchain.info, but not with 200 visitors a day. Hell, I also get 200 visitors each day on my website but I highly doubt that anyone would buy it for 50
BTC.
Do you know what a differential equation is? Or how to solve one? I did so for the map slide (basic friction equation).
Why not use one of the standard jQuery libraries and a plugin for the map stuff. Yes, you would have to rewrite some stuff, but it would have been easier then creating something completely new.
A bitcoin payment processing system, using a custom fork (fredan's ZeroMQ) which I've maintained over the recent months - to provide realtime notification of deposits and when they are confirmed. Of all the bitcoin websites out there, I'd say mine is the nicest from a user's perspective (no refreshing required, all over websocket/socket.io).
Most websites use websockets/socket.io. This isn't something new. Also, why create a whole new system when you could have used the Blockchain.info API? It would have more then sufficed for this website.
Wrote a JavaScript library (to be opensourced)... getImage.js - which provides various methods for image upload: choose file via <input/>, clipboard copypaste, webcam, dragdrop, url...
There are more then enough Javascript scripts around for this. The only thing you had to do is throw them together.
All I see is a person who spend to much time, doing something that has already been done, using stuff he made that already exists in this form. I hope that you can take this criticism without feeling the need to bash.
I, however, would like to add that your website is very smooth and that I like the way you created the map and how it reacts.
