Honestly, I don't care what anyone else does on social media, I was just pointing out why some don't go with Twitter, et al. It's not like, ok, they mine my data on the Hangout, so I might as well let all sites do it.

There's a well regarded book out there called, "LikeWar. The Weaponization of Social Media", by Singer and Brooking, that anyone interested might want to have a look at.

I'm not presuming to tell Mark anything, and even if I did, it's highly unlikely he would need your help in defending his actions. Investors Hub and Investors Hangout are two different sites, can't tell to which you are referring, maybe both?
