The way i understand it you post here via the blockchain, so your posts are on the blockchain. You spend some satoshi to put the post on the blockchain and it's there forever. These words will be recorded forever. Long live Darth Jar Jar, all hail the biggest fool of the era! That will be recorded on the blockchain forever and our children and their children will be able to read it. You can make a profile of your own name, or stay anonymous. but either way what you say will be perminant and downloaded by anyone keeping a copy of the blockchian. Maybe I should not waste such power on foolish things like a joke?
