What Joe said!
I'm still working through the details, but am already impressed enough that I have to write this post. Going to streams cleans up so much that was wrong with Famo.us.
It will take me some time to digest the changes. I'm using ReactJS pretty heavily now. I don't see an easy way to merge the two yet, possibly because a merge is not necessary. I use Meteor for server/database linkages. Perhaps Meteor/Samsara is enough.
Anyhow, fantastic job on both the framework and the web site.
