Hello everyone,
Today my article is about the two groups i joined on Facebook.
What are those and why did I choose those?
The two groups are "Los Angeles Galaxy fans" and "Marvel Addicts". LA Galaxy because I am a great fan of soccer and I am very curious about discovering soccer in United States. It is  a growing sport and La Galaxy is one of the best team in the first division named MLS. In this way I will discover a new soccer culture here and will be able to add my knowledge of European soccer in this group.
The second group I joined named Marvel Addicts is a way to discuss about new film releases, discuss about the quality of the movies with passionate people. Indeed Marvel univers is passionating and love it since my young age. It is very interesting to see how Cinema industry turned comics into movies. It is also a place where everybody can talk about its favorite character etc...
My comment was about a post on a dilemme asking if Captain America was the best leader or not among the avengers.
I think Virtual communities can help you to grow your network by bring poeple that share the same passion together. It is the same in the business field with the exemple of Linkedin. 

here is the comment that I posted on Marvel Addict group:
