The first product of the amung.us network opened it's doors: whos.amung.us. What is it? It's an embeddable widget which displays the number of concurrent users on a website. Installation is very easy, simple copy and paste the code you see on the main page into your own html pages. That's it. No setup or registration required. Stats are also provided when the widget is clicked on, primarily each page a visitor is on and which pages are most popular.
