I suspect for most people you are right, but it isn't like we can measure and quantify either disincentive.

I know the chilling effect of the widened pool of viewers is real. I also know the quality of the feed is generally terrible.

What keeps me there is the quality of the groups (mostly people I don't know) and the somewhat reliable means of contact. I don't know anyone who keeps a phone number for more than a few years, but very few change social networks frequently.
