Yes, but not how you might expect. I don't conceive of it as something where Dalton has to build this 1 big social network to eat the rest of them. Its going to allow a lot more context sensitive (in product/app/content) social networks to form that will be smaller but way more relevant. I think even after the apis are all baked there will be a robust services industry around it, collecting filtering graph walking analysis services etc. I think people looking at alpha.app.net and thinking thats it are totally off base. Not even wrong, misled by internet echo chamber.

Also, by using it I mean both keeping in contact with people I met in Alpha.app.net but using a different UI which somebody already built, but more importantly, using the apis to build new social stuff and helping to form the apis.
