@mattiaguidi Yes, I agree. The thing is that most of us have lots of different groups of peers. In my case they post in various different languages. Even though not everyone was on Twitter, there were enough people from the communities, which made the platform very effective for communication and organization. Now I feel a bit like the days of internet forums when you go from one website to another to interact with distinct people. It is not necessarily a bad thing, but it is time consuming.
