Thanks for the feed back. Actually I'm not good at explaining things,Sorry that's not an excuse. I'm always trying to improve my language and presentation skill.

I hope you're not misinterpreting my criticism. I didn't mean to humiliate you or make fun of you, I was just trying to let you know that you should improve your writing skills. I am not a great writer, but I do try to do my best and I am sure you do the best you can too. If I was too harsh in my original comment – which it now seems that I was – I apologize.

No problem man. I understood that. :)

Many times, improvements come from just iterating over the text and rewriting parts of it. Native speakers will need less iterations, and very few people can write really well the first time round.

It's a great article. Assuming English isn't your first language, I think @insertnickname is being unfair.

I feel happy about that. I want to know how I performing :).

You're right. I have apologized to OP.
