stslimited's questions might have just killed mastercoin. i can't believe nobody asked them before 
You're pathetic, people: I described it in detail several pages ago: https://bitcointalk.org/index.php?topic=265488.msg4365991#msg4365991
jimhsu also cross-posted a very good response above, as well. Thank you both.
I'm well aware of competitors, in fact I am the lead developer of one of them.
I hope others here appreciate that killerstorms comments continue to improve the Mastercoin community and its ongoing implementation by keeping some of us sane (and keeping us humble), even though he is the primary developer of a competitor.
Were not going to keep improving as quickly as we are if we dont all work together on making solid, robust concepts into solid, robust implementations. (This also implies that any concepts that arent solid or robust need to be made into those that are.)
Competition breeds excellence, but only when competitors see the good things being done on the other side, and work to improve upon them. Killerstorm understands this, and I, for one, appreciate it.
