Bitcoin has it's fault's but only because people are to stupid to adapt to it's most basic requirements. But once again you still don't get it do you? I can tell the majority of the people who post demanding for new features and/or usability don't get it.
IT'S OPEN SOURCE.
If you think something about Bitcoins sucks then CHANGE IT. If you think you can run a better business than half the people in here then DO SO. If you don't care enough about any of this, then ask yourself this question. Why are you here?
It's not that average people are stupid, its that the folks innovating Bitcoin are smarter than average about Bitcoin and have created a beast that accomplishes cool functionality with not-so-much focus on usability. Average people like functionality but CRAVE usability. Code developers in general, no matter the project, do not hold as high regard for usability as they do functionality -- this is the eternal divide between left and right brain.
Drupal CMS went through this in last couple of years. Mega-functionality in Drupal but not as usable as average Joe wants. Drupal avoided this issue for as long as it could believing "if it does cool stuff, people will come to it no matter how unusable". The community eventually paid to conduct studies about the open source Drupal CMS product, watching people on video trying to use their product, and finally realized: we need to improve usability to grow the user base.
