A group chat application (chat has to be realtime of course)
An app that pull recent tweets from the blog owner, and even tweets from other site visitors
An app that pulls recent flickr photos from the blog owner, and other photos from site visitors
Multiple games — like checkers
A “Growl” like application that shows activity for the site (if you’re using a mac and don’t use Growl it’s worth checking out)
We’re still looking into how to incorporate some kind of a library to take advantage of the huge amount of Jquery plugins and extensions that are available, but until then the basic jQuery should keep you busy. Developing applications is easy, especially if you use Textmate. There’s a bundle available that allows editing application code locally and saving it to CloudShout. When developing you’ll get a URL to include on some sample page (usually stored locally) that will load the base widget and only your application. You can make changes and view them in this sandbox, then publish your application once it’s perfect. At that point one someone from IZEA will review it (no nasty hacks or bad code, etc) and then it’ll be available for anyone to install to their blog. Oh there’s more? At first some of this was sounding a bit like Google Site Widgets (which I heard about once then never again)- - a way to enable some basic dynamic functionality. The difference is astounding though. CloudShout is realtime, open, extendable and just more badass in general. It’s also not specific to a single site. There’s quite a bit more to it, and for some you can watch Dans talk at BarcampTampa .
