It's not just a Google thing. Recently there was a HN thread on devmag.io -- they have the same problem. I measured it: in the same space HN gives me 18 stories, Devmag.io gives me barely 2. Unfortunately, I think Google people know and they just don't care. They don't want people who know what RSS is, people who care about information density; they are going after the Pinterest crowd, the sort of people who read Cos…
Pinterest crowd, the sort of people who read Cosmopolitan, watch reality shows That crowd is way bigger than the crowd that hangs out at places like HN. So it would make sense for G+ to go after them, no? This is a numbers game.
I'd argue that the issue isn't numbers, but relevance. G+ is lousy in many ways but has a few small areas of success, notably its Notifications mechanic, a community which, for me, works fairly well, and a search which while pathetically under-featured is comprehensive and fast.
Winning the numbers game for social vs. Facebook in its current incarnation is a fool's errand. Numerous people have pointed this out, including ex-Googlers pointing at the "Interest Graph" (though suggestions for following / pursuing this date to the first few months of G+).
If Google does grab the Cosmo crowd, that's fine, so long as it doesn't also chase off the Nature/PLOS crowd in the process. Unfortunately, Google's proven more than happy to sling absolute snot (as in the G+ "What Snot" feature ... oh, no, that's "What's Hot").
