While PSR-1 has pretty good universal guidelines, PSR-2 goes too far in insisting on subjective preferences (spaces over tabs, 80-char lines, bracketing styles). We should not pretend that there is a "correct" answer to these choices, just as long as they stay consistent on a per-project basis.

All told, I love site, and I hope it keeps iterating. PHP may be ugly, but it's powerful, and most of its bad reputation comes from good coders having to pick up the pieces from bad coders.
