If thoughts are random, there is no flow or structure, and casual writing leads to grammatical mistakes, it is because blogs are not examination halls. Entries are not waiting to be marked and scored, blogs exist because the world is now accepting and thriving to make freedom of speech real. This is an escape channel from the rigid and institutional systems of school or work.
I treat my blog as "conversation" over dinner, being in a place like a pub or club with friends so I am in free reign to say what I want, sometimes without even giving second thoughts.
