EUR 31.-Which are the 5 most frequented Blogs in India, China, Turkey (that have the highest online traffic rates)?

I try to get in touch with bloggers from highly frequented blogs. Which are the most frequented blogs in

• a.) India
• b.) China
• c.) Turkey

that have to do with science, ideally engineering? (although "science" in a broad sense is sufficient already).

For measuring customer traffic I think alexa.com provides useful information.

I give 50.0% of the reward each if you provide me with information on either China, India or Turkey. Thanks in any case!
