If this were something Apple did, Steve would call it "magical." 

Instead, I'm going to say it's rational. And --> It Works™.  

A new feature in River2 today, the first developed entirely in NYC, makes it easy to set up so that your river is rendered into the Public sub-folder of your Dropbox, for you or anyone else to browse. 

It wasn't my idea, it came from a smart user thinking outside the box. Not too hard to make work and it's fun. 

Here's my public river. It's updated by the copy of River2 running on my MacBook Pro. Nothing fancy, no servers, just an app writing an HTML file into a folder that's managed by the very elegant and useful Dropbox. 

And here's the writeup of the feature.  

The code was released today. ">
