It's interesting you're mentioning reddit. In my personal use, G+ actually started competing with with reddit.

G+'s what's hot section resembles pretty much the image subreddit at this point content-wise, but the browsing experience is better since most content is displayed inline and I can easily navigate it with j/k.

Now they just have to figure out how you can get hot content for certain categories. Of course it's missing the anonymity of the reddit community, so the content will probably never be on par.
