Sometimes writing about it (publicly or not) can hone your thinking and get the thoughts out of the front of your mind. It can be therapeutic if done in moderation.
Very true, when i write about my bad or good experience i can reflect easily by reading what i wrote and learn faster, i also can know if i am "bullshitting" or saying the truth, if i keep the post and feel that yes i didn't change my mind after a couple of hours i publish it, or i delete it before publishing it.
There is no disagreement regarding blogging v/s not blogging. Your approach is sound. I made my point because i sensed that this issue will tend to eat at your time. And as an external, detached, party i said what i hope someone will say to me if i am ever in a similar situation as the one you described. It can be condensed to "don't mind the people being assholes, record your lessons, and move on".
