Hi @focusnow,
Here is my review about Gwiki

Pros:

• An awesome idea to save the time of the researcher
• Provides maximum benefits to students, researchers and teachers to get a plain docuemnt
• Removes all the ambiguities or link attached to any statement
• Quite easy and simple to use
• Finishes all the complexities which may occur during the recitation of a document
• Takes good care of the grammatical error to remove them all too

Cons:

• None for it

Overall it's a phenomenal idea from academic point of view and it will ease the life of the students for sure. Great hunt @focusnow :)
