So why shouldn't you whine in your livejournal? It's your Livejournal, it's your life. Do what you want, right? And yes; I agree. Whine to your heart's content, crucify your coworkers on altars of their own idiosyncracies, complain that your boyfriend doesn't understand the special and unique snowflake that you are. In the immortal words of Kevin Kline's character in Fish Called Wanda, "Go ahead, pal! Fuck her blue!' That said: maybe you need to examine WHY you use your livejournal to write what you write. Setting it down on paper doesn't guarantee some sacredness: why should putting it down on a hard disc?
nihilistic_kid wrote this little rant about this topic (or alternately, some armchair psychoanalysis) which does have some usefulness on this topic. Personally, I think that you should write what you like-- but part of the purpose of keeping a journal is self-analysis: the ability to go back to something months later, skim through your diary entry, and go 'wow; okay, why did I react like THAT?'
This is the only thing that I look at with LJ and wonder about; how can people keep running through the same shit over and over and not get sick of hearing themselves stub their toes on the same obstacles? Fuck, PICK UP YOUR GODDAMNED FEET already!
