If you have been at FOSS.IN last year, you would have noticed that the participation level this year is significantly less. This is intentional, as per Atul Chitnis (FOSS.IN organizer). This year, the emphasis is more on "workouts" where you can actually code, rather than sit through several lectures or demos. You learn more by coding and participating. Atul mentioned in his inaugural note that less crowd actually meant people could interact and network more. In turn this means, people can learn more from each other rather than from a lecture.
The success of FOSS.IN is not going to be measured in terms of how many people attended, but how much code we are able to create in the next five days.
Come, join SDN! 
Unlock and understand Sun's hottest technologies at FOSS.IN 2008. How would you do that? It's simple! Use the Sun key chain. The brain child of FOSS volunteers, this is all set to become a rage at the event. The key chain is actually a series of cards tagged together. Each card has information on some Sun technology or link to Sun software or community. You are encouraged to walk in to the Sun stall and grab a key chain. It is everything you wanted to know about Sun, and you can actually take it away :-)
