Add support on professional platforms like LinkedIn

[habeeb-an]

I'm planing to commit this challenge on linkedIn since it will help more on a professional baackground,
so for the people who are commiting this challenge on LinkedIn will be helpful if there is great supporting community like twitter,
also recruiters can track the progress or measure On linkedIn

It's a good idea, although it's a bit more complicated for people to react to posts on linkedin than on twitter, maybe it's better to do it on both.
