Sometimes, things are silent not because nobody is doing anything, but because it's all being done in private. And sometimes still, just making the least of a public gesture showing interest will get you included in these groups.
I, for one, do a lot of things in private. But I always reply when people write to me, or write about something I can comment on. And I always seek to include people who show they give a damn, especially if they publicly expose enough about themselves so that I may judge if said person has the potential to be turned into a valuable ally (and thus worth extra attention).
I know others do this too, as, especially in the days when I was not as influential, it often happened that I was this new guy that someone picked up to turn into an ally.
Make some noise, and you may have positive echoes. Or you may disturb some people, that's all fun and games too. There is, however, a skill in making noise, and some poorly master it and usually just end up ignored by everyone.
