>>Therefore my expectation is more people will leave the service, rather than join it, in the immediate aftermath.
You think people that use and enjoy twitter (yes there are many) are going to leave soley because the brand-name changed? I don’t think so.
I said I think more will leave over the name than join over the name.
I just searched there for the words “poll x name” and several of the first that came up showed 90+% wanting to keep the old name and/or logo.
