!Hubzilla Support Forum
I see I can choose not to display my connections on my channel but I wonder if there is an option to prevent others from showing me as a connection on their channel. I think it should be up to each and everyone to decide that in just about the same way as you don't give out another person's phone number without asking for permission. Hubzilla seem to have a very fine-grained permission management but I can't find an option like this.
Another thing: I don't know if there is any display of mutual connections in hubzilla. If so I think that should also be optional and possible to choose not to be displayed as a mutual connection on other channels. On Facebook it is impossible to choose not to be displayed as a mutual connection (no surprise though...). In Skype however you can see the number of mutual connections but you cannot see who they are and that is because of privacy reasons according to Microsoft so at least some of the big companies give a seconds thought about privacy.
And I also want to thank all the volunteers working on Hubzilla, which I think is the most promising social network there is today.
