Chennai has just joined the cities which particpate in Metroblogging:
With almost 40 active sites, Metroblogging is the largest and fastest growing network of city-specific blogs on the Web. From San Francisco to Bangkok, from Karachi to Toronto, Metblogs are a hyper-local look at what’s going on in the city. Our hand-picked core of regional bloggers give each site a new perspective on daily life; less calendar listings, more friendly advice. With Metblogs, you can read about life and times in your neighborhood, your favorite places to visit, places where you’ve never been, or get a feel for them all with the daily “best of” blog on the hub at metroblogging.com.
I am one of the bloggers who is contributing to the Chennai Metroblog site -- if you go there, you can see the current list of participants. Like to join? If you would like to write regularly about the city for Metroblogging, please contact chandrachoodan[@]gmail.com.
