Oflate the number of bloggers who write in tamil language have grown considerably. I assume there could be more than 1000 active tamil blogs currently.
tamilblogs.com aggregator(which I maintain) aggregates content from about 650 tamilblogs.
Recently tamil bloggers held a get together in chennai. And it was covered by popular tamil TV channel Makkal TV. This TV show can be seen in YouTube here. This sort of media coverage for a bloggers get together is a good sign. This will help to get attention of the public towards blogging. And this will lead to increase in the number of tamil bloggers.
I would love to see a strong & responsible tamil blogging community which will act as an alternate media.
