I’ve just run across a website that might have interesting possibilities. It’s called BigThink, and its aim is to be a sort of online multimedia venue for the exchange of Ideas. I’ve only just started poking around in it, so I haven’t anything much to say about it so far — and being so new that it doesn’t even have a Wikipedia entry yet, it might take a little while to gather steam. It’s the kind of thing that could go either way: I’ve learned how easy it is for these promising ventures to flop. But it could turn into something worthwhile.
Anyway, have a look here.
