To be honest at the beginning i was a little skeptical about the communites's potentials. It was sometimes a funny game to complete the mission we were asked to complete as give a like to an article and so on. But day after day i started to ubderstand how much is paramount the sharing of knowledge, and how the communities is a mine of precious info. Nowdays i am used to login almost daily checking for new articles in my area, and everytime in case i need to research on previous experience. I hope the communities will continue to grow since i think it is a very powerful tools for everyone on the field.
