Good point, well made.Technically, not replying at all in this situation would be classed as bad social media management. You don't reply to trolls, but you should always acknowledge when you're asked an earnest question, even if you don't directly answer it.
So I don't think we can read very much into what Bianca's posting, given she hasn't answered the actual question. They clearly do have a comms strategy in place around it, though.
I still think if the plan was still the plan, and the ride was still planned to be open this season, it's not really giving anything away to say 'yes, update soon'.
