Thinking about 'So'

Thinking about 'so'.  About how I was kinda enjoying how I use the casual 'so'to begin a sentence, talkative-like; an interrupted beginning to a thought.  But!  It's the blogging cliche, I'm hearing it everywhere, Bridget Jones and all the bad writers the girl blog movies are about (even if I like the stories and the movies are good, the writing's pretty bad!)  So.  No to so.
