If you will ask a specific website then its hard to tell.
the most favorite website for me will be Techgig. if you ask why then i like read the technical updates available on it. It has helped me a lot to improve my knowledge and global technology state. But the main reason is that i look forward to those new upgrades in technology of the world.
Depends upon purpose,
I mean if i want to search something there's google
i am bored then i can go to quora, facebook, youtube, yahoo.
There are other websites for other things.
also i go to awwrds for creative website examples.
Hello, I think that Google search engine and social sites are most powerful sites like as Facebook,Twitter,Link din,Pinterest and YouTube etc because it helps for internet marketing and we favorite them.
Thanks
