Compelling Single Page Applications (SPA)

A couple of months ago I had blogged about TiddlyWiki, a Single Page Application that allows users to Get Things Done (GTD) using a wiki paradigm. In comparison to other approaches to creating applications that work both online and offline such as Google Gears and Adobe AIR, in my opinion the SPA approach is very clean for many applications albeit not as powerful as Gears or AIR. Well, I got further endorsement of the power of such SPAs with these two new gems that I discovered:-

1. Your Timesheets (http://yourtimesheets.com/): This is a SPA that allows you to track your time and supports Full-time, Casual, Contractor, Flexi time and more
2. Your Form Builder (http://yourformbuilder.com/): This SPA allows a user to create any Form using a super simple interface. So a users simply selects Text Boxes, Radio Buttons, Check Boxes, etc and is able to create compelling forms in seconds. And whats more, you can publish these forms (even by email) to other users to fill-in and collate the results. Simply superb !
