Dimdim works like this

Mr d d Ganguly replied as follows

Dear Ajit,
Thanks for your post. You had asked about how the company works.

It’s really very simple: great team and a compelling vision.

The vision for Dimdim is simple: we see a world in which organizations of all sizes will have access to web collaboration software. We have started this journey with a focus on web meeting software that allows rich-media real-time collaboration.Our Open source strategy enables us to distribute our technology pervasively. Our product has already been downloaded 7,800 times in just one and a half months. After the community downloads the product their feedback about the product is even more valuable. Community members report bugs, submit feature requests, and delve into the code to point out why the software behaves in a certain manner.The relationship with the community is exhilarating. We feel that we are part of a much larger team
– the Dimdim Team.
Best wishes.

I hope he succeds in his endeavour and Let Open source flourish.
