so once you vote on one the vote will correspond to the value of the content for ever.
I accept this, even in normal posts, I can change the entire content after voting frequently(don't worrying about down voting at all), but I have some discipline not to change(which could to lead to confusion) and just type 'UPDATE: ... ' and add further content. Let's hope for the best(discipline) from the users of this system not the other and try this 'voting enabled on the user's home node'

-- In accordance with the prarabdha of each, the One whose function it is to ordain makes each to act. What will not happen will never happen, whatever effort one may put forth. And what will happen will not fail to happen, however much one may seek to prevent it. This is certain. The part of wisdom therefore is to stay quiet.
