I was very happy with Wikipedia.
It explores world to us. We can see n number of categories like movies, plants, books, and about some popular celebrities etc.
It plays a prominent role in everyone's life.
For some people it is like a guide book for them.
If I want to know about a unknown thing, I used to see in Wikipedia. The matter that present in Wikipedia is very useful to us. N number of times Wikipedia is helpful to me. From childhood onwards I was using this application. Thank you
