The blog of Superfeedr, a service for pushing RSS and feed updates, covering feed technology, PubSubHubbub, and engineering choices.
HN links it for RSS and feed-related discussion, including the state of RSS readers, its realtime streaming API, and the Google Feeds API shutdown.
I was just discussing about recommendation engines with a friend yesterday.
My pet peeve is that i find a lot of the companies,datasets,research focus on the positive aspects of recommendation. There is probably a lot more negative data we're missing out on, which is not being collected a lot. That data consists of things i would "hate". I would want to chart out a hate pattern of the internet and an anti-pagerank of sorts.
I was reading a post about the same thing yesterday(1), linked along with some questions of my own at http://blog.sidmitra.com/where-is-my-dislike-button.

Thanks for clarifying your intent, but I think the original commenter is right, there seems to be little here so far that PuSH cannot do.
In fact there have been recent proposals for PuSH to gain JSON message formats (I believe superfeedr is now providing JSON data as well).
That said, there certainly seems to be room for more PuSH hubs, perhaps that is a direction you can take LiveDirectory.

Fanout's great for powering a public-facing realtime API. For example, you can see what Superfeedr did with it here: http://blog.superfeedr.com/stream-superfeedr/
If you're not making an API, and you're just pushing data to your own client applications that you control, then Pusher and Fanout are more or less the same. Although you might like Fanout's simpler pricing model and our more open philosophy.
Not too late to consider a switch to Superfeedr https://blog.superfeedr.com/google-feeds-api-welcome/
There are plenty of alternative readers http://blog.superfeedr.com/state-of-readers/
