I partly agree with you that some bad beats are just not worth thinking about, or telling about, or hearing about and its best to just move on.
But, we also are, a poker comunity, who talks about poker and "bad beats" is a section.
a topic related to our day day situations and feelings, to tell about after our chipstack is finished, and we stand up....
you wont find an article about fixing your car though, simply because we talk mostly about poker
some bad beats are just uninteresting, as you say,
as the one i had on pkr at our thursday league:
my 66 lost all in preflop to someones 33 at the final table - bad beat.... but not worth telling
lol.
PLAY ON!
