Not to be rude... but are you sure people fully understand this? Snapchats are supposed to be seen at most 10 seconds. Snapchat frequently has little bugs where the snap doesn't show up for it's full amount of time.
I hate to say this because I genuinely like the idea... but this website seems shady to me. They are bragging about reverse engineering an API, and IMO, at best, spamming users with a 10 sec disclaimer saying their photo will be posted online.
Overall: Nice site. Congrats on the technical side. But I really don't think I can condone this.
