No point having a new board for it, unless it's more finely subdivided or something. Otherwise just have the glass bot post in the normal add-on board.
That would end up spammy.
Thought about that too, just didn't want to spam up the add-on board. Plus, most add-ons uploaded to Glass aren't new releases, they likely already have more detailed topics going.
There could also be an option whether you want it to generate a topic for you or link to one you made yourself
