And my point was that, from what I can tell, that proportion of trash::value has been increasing on all social media in (more or less) lockstep. If anything, I'd say Facebook has seen the most precipitous drop in quality, not Twitter. So much so that I don't even log in anymore, and I was veritably addicted during college.
I even get sucked into contributing at times, which is why that descent into trash _works_ so well. I hate it, and I visit HN less and less as a result.
