you can edit for 7 days after you post, but, yeah, it's permanently in the blockchain no matter what.

Please explain. If this is your own piece, wonderful work.

oh no!!! don't leave pleeeeze u juz got heeerrrrrrre. fuh

Yeah, so each post, every comment, every transaction, everything on steemit is part of the blockchain and ireversible. This is actually good because it can't be censored. It's also good because no one can shut down steemit either. Just like they can't shut down the peer-to-peer networks for the same reason. BUT don't edit your posts! Live in the moment. Put it out there. Fuck what these people think anyway. That's not what we're here for. Everyone on Steemit is kissing everyone else's ass for an upvote. Fuck that. Let's show them what creative people can do with a new technology.

man i wish you would come back and help me make steemit cool
