con — It's sort of minor, but within "my list" or tagged articles, the date it displays and sorts by... is "when the user saved the article", and not the date the article was published. I don't know why, but I find this pretty irritating. It would be nice if there was some user setting that could toggle this, but I know that UX folks like to simplify configuration options and avoid such minutiae.
Granted, the two are usually aligned... but once in a while they're not.
con — Frankly, its recommendation engine isn't the best. I prefer to scour other news sites (Google News, Axios, BBC, ...) and then use the Pocket browser extension to add an article to my saved items list.
Though there are ways to improve its suggestions, I suppose.
con — while articles can be sorted by latest or oldest, the date that it actually goes by is the "favorited" date (hover your mouse over the text that looks like "2h", and it'll show the full timestamp), but at least it shows A date, unlike Pocket!
con — There are several features that I really like from the "Pro+" level (see list below). But $8.25/month isn't cheap, considering this kind of service is offered free elsewhere.
Twitter — a microblogging site (many news stories have a "tweet this" icon built-in)
con — Articles are never shown alongside their publication date (though their "tweet" date is shown), which strips them of some very important context.
General types of sites:
social news aggregators — this term seems to be mostly associated with sites like Reddit or Digg, but not many others
