I think overall these tips are great if they're targeted at new players who know poker from tv and want to give micro stakes NL or tourneys a shot. Basically against bad opposition they'll be correct "enough" of the time to not get crushed too quickly.

That said, I agree that these really are just default tips when you know absolutely nothing else about the game you're in or the players you're facing. Almost every piece of advice is situational, which is fine, but dangerous once you play against players that play situations too.
