There is some sampling bias in terms of what's discussed, but you can still get good information about the good moves and missteps each company has taken. I suspect that mistakes like "Didn't listen to users" are valid mistakes whether you're talking about Infogami disappearing or about Intel's Pentium II bug. That said, there's definitely sampling bias -- but these are more fun to read because it's hard for failed founders to be honest about what was their fault.
