One thing that always bugged me about the criticism of the Diaspora release was that people criticize it like it is production software when they clearly stated it was a "pre-alpha developer preview". Who cares if they didn't have security checks? They could have been just waiting till later to add them all in.
I know when I build I like getting the scaffold/mvp up as quickly as possible ignoring security because hey, this thing isn't out in the wild, and do my due diligence on security after I am happy with the prototype.
