Unfortunately, my first association with Agora was "agoraphobia", fear of public places. But perhaps we could use that to our advantage, and talk about our "competitors" having Agoraphobia 😉
As for Tcl -- I think it's less of an issue than people think. The reason most of us were drawn to ACS in the first place probably had a lot more to do with Philip's tutorials and book than anything. Someone ranted about this a couple of days ago, and I fully agree: we need to make it easy for the newbie's to get involved in our project.
The name Agora is growing on me too -- I think I'd vote for it.
