and that name is clearly not bit
"bit" is already in broad use on reddit with that tipbot. Average tip amounts seem to have fallen as a result, btw.
Average tips have fallen because most people use the random feature instead of choosing specific amounts. On top of this, Bitcoin has been in a sticky situation lately with the news coming out and people are afraid to let go of too much when the price could shoot up at any moment. It has nothing to do with changing to "bits."
