How do you know any given crypto project only has two feet? :D
I really like the bridging ideas for no other reason than I hate siloing and the associated delusion of exclusivity. I'm sure there's plenty of other advantages and problems to go with it XD
I am being generous. Some don't have a leg to stand on ;D
I think in general, bridging would be a boon for all concerned - the negative for Hive is that Hive people might travel elsewhere to explore -and since it is the or among the largest crypto communities, it could get quiet for a bit. That isn't too much of a risk though.
