Great posts. I'd like to add that 'OWLs' (one way languages) and 'MTOWLs' (more than one way languages) made the most sense to me. WiB and BiB makes sense too, because I knew what you were getting at. Having used many programming languages I've settled on 'WiB' languages as my preference. Though I consider WiB to actually just be better. :D

Complexity creeps in too quickly and too easily. While I don't like the WiB moniker, I definitely prefer OWLs. :)
