Ruby people fucked off, Java people fucked off, I have come to the conclusion that you can trust anonymous people on the internet with money for drugs and you will receive them, but if you pay someone for code they will fuck off. Hopefully scalability would be a problem, fifty people mixing messages together does not lead to much security. If a system is as point and click easy as a php forum and offers anonymity and security better than Tor or GPG, I would imagine it would be used by a decent number of people. Especially since there are so many people who are always complaining about how much a pita it is to use GPG. Those people would love to double click on an icon, have a program that looks nearly identical to a phpbb forum pop up, click on the pseudonyms/groups of their desired message recipient(s), type their message in, press the nice looking send button, and not have to know how to do anything else. People who know how to use GPG will like this as well, although may be more attracted by elliptic curve crypto offering nearly double the strength of RSA 4,096, or by provably secure mixing to protect them from end point timing correlation attacks, or padding to protect them from fingerprinting attacks. I do know some about security, particularly traffic analysis, but I have thus far focused far more on learning theory (such as what the types of attacks and defenses are, how they work, etc) than the skills to implement such a system (of attacks or defenses) with any language. The bulk of my "applicable" security knowledge is related to operating system hardening and server administration. However now I am focusing much more on learning implementation skills, and I am pretty satisfied with my theoretical knowledge (especially of traffic analysis, when it comes to crypto I know more than most but less than most who try to learn much about crypto )
