The problem with the likes of Chana Tarkari is this:
Look at how he starts his sentences in his last two posts:

" I thought I would pack up for today, ..."
"i do not want to push this discussion behind "tamang" vs "zuckerberg" nor want to talk much about individual.."

So basically, chanatarkari is an individual who thinks about himself a lot and who has the habit of throwing in arguments that has nothing to do with the discussion at hand. Who cares whether he would pack up ? He can always hide his tail behind his two legs and run away. Similarly, he starts this Tamang Vs Zuckerburg, makes all assumption about Tamang (basically calls him a corrupt man, inefficient teacher and what not) and when pushed, he wants to say he doesn't want to push the discussion. This is the extreme of shamelessness. I totally agree that there is no point in talking to individuals like him because they have no position in this debate that they can defend.

And what is this with nagarikreport? 

When did Dixits become communists? Not that this is an honor, but it shows the extent to his knowledge.

Basically, the lesson I get here is that there are bunch of losers who are quick to brand any successful person as a corrupt. These people don't try to do anything. They just hate successful people in Nepal. They don't recognize the changing nature of Nepal. yastale kina feri bekar ko discussion ma bhag lina pareko.

Ashu , good inputs there. Not that it made any difference in the mind of the person who refuses to learn or admit his mistake anyway.
