I just announced on Scripting News a new product -- River4.
It's the next in my series of river-of-news aggregators. This is the first that does NOT run in Frontier, it's written in JavaScript and runs in Node.js.
There's a lot of information about it on that site, including a link to a new support mail list for River4. Please don't post questions or comments about it here since they would be off-topic. I just wanted to announce it here because it's a good thing for River3 users to know about.
