You're allowed to. We are then allowed to think you are an asshat for doing it.
Sharing cautionary stories is good. Learning from others' mistakes is good. Jumping on these as an opportunity to put someone down for the purpose of self-promotion ("mostly self-inflicted", express your surprise) is unkind, probably bullshit (I have seen soooo many people pretend to be above problems and then run smack into them), but most importantly: it shits up the dynamic where people are willing to share their mistakes, allowing group-learning. It would have been the easiest thing in the world for rachelbythebay to not make this blogpost and thereby avoid providing an opening for asshats like yourself, but I'm glad she made it anyway, even knowing that you would take your shot, so that everyone else could learn.
