I've noticed recently that planned posting doesn't usually work as well as stream-of-consciousness.  Planned posting is a term I coined 4 seconds ago that refers to the act of thinking of something to write about, writing myself a quick little note as a reminder, then writing about it when I have some free time.  It usually happens like this:  I'll be watching TV at night and I'll get annoyed at something, so I'll write myself a little note about it and plan on writing about it when I have some time at work.  But when I get to work 12 hours later, I'm no longer in the same mood and I don't have the same feelings concerning the topic I wanted to write about.  So I'll put it off for a few weeks then write some stupid thing about it just to get it off my to-do list, or I just won't write about it at all. 

Some of my "best posts" happen out of the blue.  I'll be doing some work and something will happen that makes me want to complain a little bit.  Or I'll think of something randomly and write some huge, life-changing post about it.  It's basically like stream-of-consciousness writing, which (as I understand it) is just a flow of words and thoughts without anything necessarily linking them together.  But my stuff is usually somewhat coherent and mildly linked together, so I have that going for me.
