It is also nice to know, that there is something called nanopaprika, when one would like to catch the attention of that bit of guys who might be interested in atomic-scale simulations (read nano-techstudents and docs) out of one billion Indians. On nanopaprika it is also possible to upload videos related to nanotechnology or just make an update on job openings, seminars, webinars or whatever might interest the community.

Actually nanopaprika is a community in English, that is as international as YouTube or any other social media, but with a much more specific target group. It just seems to be more popular in India.
