I'm all in favour of developers contributing, replying, announcing so long as it's clear who they are. That just improves everyone's understanding.

I'm not sure why Scrivener is offering a discount. They always used to for NaNoWriMo but I don't remember others. And their versions have been remarkably long-lived so far. I can't imagine them wanting to go through the pain of producing a v4 for Windows. otoh, for general users, the whole design feels rather long in the tooth compared to more modern, frequently more expensive subscription-based, programs. Maybe they need more new users because that's their only source of income.
