In /m12 David asks whether I think ThoughtHorizon is commerical or not.

I have to say I don't know but my gut feeling is not. I don't see any evidence of commerical activity: no adverts, no sign of anything for sale, no offer of services.

So I'd turn it around: is it meant to be commerical?

Of course this leads to the question: What do we mean by commercial in the first place?

I tried to define that for myself on the tube last night and didn't get very far!
