The release of pre-alpha source code for their Diaspora social Website was only a few hours old on Wednesday when hackers began identifying flaws they said could seriously compromise the security of those who used it. Among other things, the mistakes make it possible to hijack accounts, friend users without their permission, and delete their photos.
This is actually a good thing if the right people decide to embrace this project to show how open source programming allows for better security. Why? Because the code is open to everyone, which means that yes, the miscreants are going to see the weaknesses, but so will the people willing to donate time to make the project better.
