Facebook launches sharing features much like G+. Who do you share with? (facebook.com)

When sharing you can select who can see your content, also quite similar to G+. http://www.facebook.com/about/sharing/

Together with making groups, you can now easily post things to different groups of people... http://www.facebook.com/groups/

For me - being a person who has many different fields of interest - sharing different things with different people is a very welcome feature.

Yet, a question arises: I often read stuff about awareness, opening your heart, sometimes it may have a bit of a 'new age edge'. That's fine for me, but it may push a button in some people, which lead to some quite rude or negative comments on what I shared in the past. Which in turn makes me share less ... Choosing who to share with could 'fix' that, because with more possitive comments I would feel more appreciated for sharing, which would make me share more ... Yet how can I justify denying some people the chance to read what to me opens my mind?

Do I select with care, or do I care less about the impact and share nonetheless?

It's strange to find that I thought I was going to write here about how I applaud these (somewhat coppied) features, only to find out during this writing that I actually feel pulled to not using them as much as I thought I would.
