Mr Sarath
We have spent a lot of time and energy on a subject which may be best called "the Cathedral and the Bazaar"(CatB, Eric S. Raymond).
I remind all readers: the content of Plain ad Simple English (PSE) is in a blog (not an academic journal) "Learners' Web", under "การศึกษานอกระบบ การศึกษาตามอัธยาศัย" and the cover story is under "วิทยาศาสตร์ เทคโนโลยี" (because of PSE's algorithmic "learning" iterations) of gotoknow.org.
PSE is like other 'free software', it comes with this 'standard' disclaimer: (SOFTWARE PRODUCT=PSE, THE PROVIDER=sr @sundarekas)
This SOFTWARE PRODUCT is provided by THE PROVIDER "as is" and "with all faults." THE PROVIDER makes no representations or warranties of any kind concerning the safety, suitability, lack of viruses, inaccuracies, typographical errors, or other harmful components of this SOFTWARE PRODUCT.

I think I am being flooded by negativity.
I will go and have a cold shower ;-)
