This is a great place. I am glad to have the opportunity to have my preferences at Geni.
The concern I have about the relations in India is that the calling names differ from the English names. People are missing their cultures and that is because of Anglicization of everything.
People have started introducing their parents, relatives and grandparents with their English names which makes a lot of confusions.
For example maternal uncle is called MAMA in Hindi where as the English word is uncle. And the paternal uncle is called CHACHA ... but still called uncle. Both are uncles(maternal/paternal) but generally they are called uncle only in English. There is no direct pointing in general English.
Moreover I feel that the Hindi names will give a different feeling to the users ... plus they would come to know the relationship names if they don't know.
I need to spend some time to get the Hindi names so that it may help you developing it. This will increase the traffic and references drastically.
Thanks, Vivek Pohre
