About LinkedIn profiles and language switches

Thesedays there are several posts talking about why people decide to write in English having a different mothertongue. If I get a good answer about why people write their LinkedIn profiles in English and not in their own language maybe I could change my mind.

LinkedIn users also play on this league, don´t they?

Don´t get me wrong. This is the only space I really own, and in my apartment I walk naked, I can do whatever I want. I wrote in Portuguese for 3 years and people out there really appreciated. If somehow I get to know another language I will also try to write in that language. Why not?!!
