“Looks”
That’s the first answer we heard when my team of Wikipedians sat around a table and raised the question. Quite understandable, unaided by any description, although we can’t do anything about it. However, Wikiwand did it. They solved the problem by transforming Wikipedia into a “new” beautiful site as if by waving a magic wand on it. That's a cliche, of course, but let it pass :)
Now, I am looking for serious answers.
It will help us in our non-commercial project, part of which is the construction of a Wikipedia-related website. Kindly recommend this, if you don't mind.
Thanks.
