I think there is NO end to the discussion about plagiarism and to be honest it is NOT just the problem that the bloggers face. Corporates, film makers, music directors and even brand promotions/advertisements....it's in people's minds to be INFLUENCED. Saw Dhoom 3 yesterday and read so many status updates that it has been "copied" from "Prestige" ... (though I thoroughly enjoyed whatever I saw)...people said a lot about the movie Barfi too, but then that was again a superhit. The point is what you decided to term it...copy or inspired :)
Lakshmi, since I have interacted with u in the past on twitter, all I can say is....look at the positives...try to understand this, your post must be good enough to draw ppl into the inspiration centric mood :D... jokes apart, very difficult to stop people really and Renie knows how I myself have countered a plagiarist out here. :)
