I have different definition for many different website. For me they are something like this:
1 . Youtube - Baby sitter.
2 . Twitter - Tool for sharing political opinion and trolling.
3 . Facebook - Marriage registrar. Also acts as testimonials for car purchase.

There are many but i think these were very popular websites thus thought i would mention them. If you are here for information of Block chain then it is definitely a good place to learn a lot of crypto currencies and all but this is not a informative blogging website. It has its own shortcoming. But ya it is 1000 times better than steemit.
