As promised last month, here is a small update on the real-time feeds market.
First, I’d like to insist on the method we use to collect these statistics. For each feed, we always try to determine what is the best way to get its content and push it to our users in the timeliest manner.
If you were building a similar infrastructure to ours, assuming you’d support PubSubHubbub, RSSCloud and SUP 1, here is the breakdown that you would get.
Compared to last month, we have three times more feeds and the proportions evolved significantly.
As you can see, it’s pretty obvious that there are less and less feeds that you’ll be actively polling (still about 75% though).
This is mainly due to the fact that we added white-label hubs to our service offering.
Similarly, we now host official the Posterous hub and Backtype hub (among others), which means that if you poll their feeds, you’ll use Superfeedr :) As a matter of fact, we host the hub for 48% of the hubbub-enabled feeds that our users subscribed to.
1 We implemented many other ways of getting feed updates, including some specific APIs and other techniques.
