Lazy programmers who didn't read about how users don't read anything:
The main purpose of this screen seems to be so that users blame themselves when they hit reload and find themselves blown back to step one. Oh darn! I'm so stupid! say the users. Yes, that's what happens. Watch any usability test where the product is failing - the users inevitably blame "their own stupidity." Better that 100,000 users should feel stupid than one programmer admit he didn't do a very good job.
Don't let anyone tell you that as a programmer you don't have to make moral or ethical decisions. Every time you decide that making users feel stupid is better than fixing your code, you're making an ethical decision.
You’re reading Joel on Software, stuffed with years and years of completely raving mad articles about software development, managing software teams, designing user interfaces, running successful software companies, and rubber duckies.
