Breakage of lightweight components is to be expected, especially when
the one using them is not a lightweight. Ritchey cranks are neither
the best nor the worst in mitigating the shortcomings of their
lightweight design. If you don't want to break any more cranks, use
some of a proven, conservative design that weigh more, or are known to
be made of a stronger material, than the ones you broke.
Usually these events are a result of highly stressed parts in
combination with materials flaws or design flaws that wouldn't have
caused failure if the parts hadn't been so highly stressed.
Manufacturers shouldn't make weak, flimsy parts for public
comsumption-- but by the same token, cyclists shouldn't buy very
lightweight, inexpensive parts and expect them to last indefinitely
when ridden hard.
There's nothing off-topic about posting a link to Pardo's pictures of
broken cranks. Surely many of them failed for the same reasons that
your crank failed. If you send Pardo some decent pictures of the
broken cranks at issue, he'll probably add them to his page.
