Well, the initiative from Mozilla labs to start coding in the cloud is not a new idea, given the fact that we have encountered child-computing ;) (i mean html coding) using web editors for quite some time now.
The normal claims of
- Compelling user experience
- using open standards
- extensible frameworks
- etc.
for a cloud based IDE - like environment where I must 'upload' - 'write' - & - then 'download' to export it to my dev/production server ??? umm .. i think i may skip this one.
BUT - that being said, this is a great initiative to learn how the Mozilla guys are using HTML 5 (proclaim ably the next big thing in the web .. ask google !!) So worth joining the band wagon to see where things are headed in the not too distant future.
