WordPress has announced that it has added RSSCloud to the millions of blogs it hosts? So what, you say? What it means is that blogs can now act as real-time discussions, the way Twitter works. That means that your feed reader, if it supports RSSCloud, will get updates instantaneously rather than every 15 or 60 minutes. The ReadWriteWeb blog puts it in perspective:

Real time updates could enable several things. Faster distribution of blog posts, more compelling conversations in real-time and a renewed timeliness for blogging vs. services like Twitter are all likely consequences. The list of possible technical developments on top of RSSCloud could be as open-ended as the developments enabled by the core of RSS.

RSS has made blogging viable by freeing readers of the requirement of visiting each site they are interested in. It has made podcasts subscribable. It has made wiki change notifications trackable outside the mess of the email inbox. It has made search a persistent action, instead of a one-off occasional delayed reaction. RSS is mixable, mashable, parsable, filterabile.

Now RSSCloud could add a real-time dimension to all of that. The paradigm just got a very big vote of support.
