The news is great information indeed considering the appeal of Mozilla products and the latest developments in the Web applications field. The browser being a gateway to the internet, it is more or less like a generic operating platform for the internet.
Also, with the latest projects in seamless integration of offline applications with online utilities and incorporation of more dynamic media on the web, a lot of developments are happening at Mozilla.
Offline-online applications integration will be emerging as the next arena of brand wars with Adobe and Microsoft pushing for their AIR (Adobe Interactive Runtime) and Silverlight platforms respectively. Mozilla has a similar effort known as Prism. Google also has a set of APIs for offline-online syncing called Google gears.
The new joiners from the Humanized team are expected to bring a lot of innovation to Mozilla products.
