Posterous.com now publishes real-time PubSubHubbbub feeds for every site in its domain, the company announced yesterday in a blog post about a number of major revisions to the site. That means that real-time savvy content aggregators will receive Posterous content almost instantly after its published, instead of waiting as much as half an hour to poll the site for updates.Blogging and stuff sharing service
The company is using the service Superfeedr to outsource its Hub management. Posterous joins WordPress, Blogger and TypePad among the popular publishing platforms to offer real-time feeds.
Posterous combines very easy publishing of original and curated content with an in-network subscription reader. If you're familiar with Tumblr, this is similar. Posterous is much smaller than Tumblr but this Fall introduced a feature to import Tumblr blogs into its own platform.
Superfeedr is a service that consumes content from publishing platforms in a wide variety of ways, including polling if needed, and then offers a republished feed in real-time formats including PubSubHubbub or XMPP. Other services using Superfeedr include Six Apart, Adobe, Twitterfeed, StatusNet and SmackSale.
It's probably just a matter of time until Google Reader implements real-time feed consumption, but in the mean-time real-time blog feeds are quickly becoming a substantial portion of the real-time ecosystem. That ecosystem is best known for its high profile constituents Twitter and Facebook but now already includes far more than just those sources. These are very early days in the real-time web but the pace with which publishing platforms have adopted the paradigm demonstrates how easy it is.
Publishers making the move to real-time feeds not only offer their users a chance to appear first in front of readers, they also substantially reduce technical infrastructure requirements for publishers burdened by the need to poll periodically to check for updated content.
