@timbray I do!
But I think this will mostly be a staff decision, now that they have their marching orders.
I suspect they'll start posting to all the platforms, rather than picking one winner.
Unfortunately if any platform gets left off the list I suspect it will be Mastodon, because that would require either choosing an instance (which could be perceived as a political choice, which staff will probably want to avoid) or setting up their own instance, which would have a higher bar with respect to research, planning, and implementation.
It's just for the City Clerk account in any case, which is pretty obscure and housekeepingish.
