Im not necessarily comfortable in starbucks looking at a trending page with articles about alexa tying up moe the monster, even if theyre greyed out and even if I don't click on them.

I'm entirely comfortable with viewing a Trending page in Starbucks that shows a SFW first image and a headline that clearly states "NFSW, uncensored". I just won't be clicking on that post at Starbucks. YMMV.

To me the refrain this site has a bunch of porn on it. if you don't want porn don't click on it is one thats apt to chase a lot of potential users away.

Look I'm not opposed to features that allow people to customize what they see, and create a family-friendly or work-friendly view if that's what they want. But global view that are intended to show everything that is on the platform (e.g., for curation purposes) should actually show everything that is on the platform (unless specifically customized otherwise).

That said, I also believe that the users you think will be alienated are already well-served by Facebook, etc. If we can also accommodate them by providing filtering and customization, fair enough, but focusing excessively on that market is probably a big mistake.
