The searchable digital record is the key difference. Statements out loud to one or more people are often: A) tailored to that audience, B) carry much more context than a piece of text on a screen, and C) are a way of growing and exploring new ideas without the commitment of recording them to an easily searchable record for the rest of time. The long-term ramifications of saying something stupid in a conversation that isn't recorded are far less severe than they would be if every word you said was recorded and searchable forever. A tweet is really more like submitting an article to a publication of record with your name and face attached to it. But, the ease with which twitter allows people to post makes it seem more like an ephemeral conversation. Anyone who has been burned by a stupid joke tweet from 10 years ago learned that lesson the hard way.
