Ask HN: Is Sharing HN Threads on Facebook, Twitter and Reddit Advisable?

Sometimes I see threads that I think might be interesting to a large group of my friends on Facebook or even just to get an outside opinion from regular internet users (I take the HN crowd is mostly technical). My only concern is that at the same time, I don't think they are the typical HN crowd. They like trolling and stuff so I generally don't share to avoid dilution in the HN community.

Do you guys ever face such conundrums or it's just me?
