Now-a-days, i spend a lot of time in Orkut.
Though there are certain features that can be enhanced further, overall I really like the features available in Orkut. I m getting more emotional meeting my old friends through this service.
Another most interesting feature in Orkut to me is the algorithm they are using to find Related Communities. Say for example if I am in the Vairamuthu Fans
community, the right side bottom frame shows the related communities like Vaali Fans, Illayaraja, etc. For a Sachin Community, the related communities frame has Dravid, Dhoni, etc. Why I am so excited is that, this is working perfectly even for communities that aren't related to any popular personalaties. Amazing!!!
The brain behind this algorithm deserves a Big Salute. Great work Team!!!
PS: Need to search and find how this is implemented. The Big G, please help !!!
