I'm writing my Degree thesis and I have decided to focus it on "word of the
day/week" Web sites, and this one is one I've chosen.
That is why I need some information on how this website works.
this is what I need to understand:
Who chooses the word of the day(or the theme chosen) every day and with
which criterion. Are they related to any particular event?
- From where do you take the definitions (which particular dictionary)
Do you think it is just for mother toungue or for learners as well?

and the most important part:

why did YOU choose this web site instead of another one?which is the reason? what do you love about this feature(one word a day)and if you have any purpose...if you can, be detailed. I mean not just say....it's interesting, nice and stuff.....

thank you ver much!!!!!
