OK, I have to say this: in GNU Social there is this wonderful thing called Groups. You can follow a group and then you get any message which mentions the group, and, if you follow a group, you can mention it in a message and everyone will receive yours. Without anyone having to specifically follow anyone in the group... I'm sure many have already pointed this here XD
