On the international Hardy scale (IHS), beer is much less douchy than Ed Hardy
Much more poetic than Thomas Hardy
Funnier than Laurel and Hardy
And tougher than the Hardy Boyz
Seriously, though, once you are on the forums long enough, you notice that about 80% of those who think they ruined their beer end up with perfectly good beer. About 19.2% make a huge user error that causes their infection or other problem, even if they have no idea what that error was. The other 0.8% actually have screwed up beer through no fault of their own.
It is difficult to mess up a batch of beer if you practise good santitation and proven recipes!
