I'm not gonna talk abt. Kamal's reference abt. Maraththadi, as he has already clarified. I would like to say a few words on of the few wonderful groups which makes writers out of ordinary men(and women).
For all who haven't been to Maraththadi, itz a wonderful place where the people can talk abt. anything on only one condition, 'solla vanthathai nErthiyaakach cholla vENdum". I would say a best thing could happen to a budding writer is some objective criticism and encouraging words. You can get a plently of both at this group. I dont think I could say more if I say people like Dr. Jaybee, Harikrishnan, Anand Raghav actively participate in Maraththadi and genuinely look to help out.
A lot of our PS grp. members like Mathy, KVR, Pavithra write actively and amazingly in Maraththadi. Yours truly also blabbers occasionally;-)
