Well, once the site had filled up, there was not really any more demand. Ean and myself, who were doing the orders, went off to do other things. I was working a full time job at the time as well, so that was kind of a relief, because even at 25 years old, 16 hour days take their toll!
I'm English and typically squeamish about money but suffice to say, the site really did make a million dollars (before tax). Alex paid me generously for my services and it paid for a good chunk of the deposit on my house!
Alex has gone on to do a lot of cool stuff. I'm currently principal software developer at Box UK and involved with tech meetups and open source. Oh, I do still rock the human beatbox!
