Languages in India
India is the home to one-sixth of the world's population, and the number of dialects spoken by its people is well above 1500(Ref:Wikipedia Entry). The number of officially recognized languages is still large, at 22. Hindi is the language with the most wide-spread use, but a large percentage of the populace does not understand it. By far, this will be the country for which Geni and its users will have to do the most work for localizing, especially due to browser / Operating System issues in displaying Indic scripts.
'Broadband connections' (defined in India as always-on connections of 256kbps and above - as opposed to 2MBps in other countries) are available in all urban areas, which accounts for just about 30% of the population. The rural areas are still stuck at 56kbps dial-up connections, which usually means a much lower usage of internet. Even though the official requirement is just 256kbps, most ISPs have affordable plans for 2MBps connections.
