Since joining, to comment on a distant acquaintaince’s post, I’ve been marketed to incessantly with loud, flashing banner ads. I’ve been invited to join two “communities” — neither of which I know a single person involved with, nor in which have any interest. I can’t tell what’s an ad, what’s part of the site, and what’s a commercial tie-in. Overall it leaves me with absolutely zero interest in participating in any meaningful way.
