So, Tumblr went real-time last week. Cool.
The added support for PubSubHubbub (can you say that ten times fast?) proves two things:
- Tumblr’s got its dukes up. Heavy competitors like Blogger and Posterous (which both added support for PubSubHubbub earlier this year) look like they’re in for a worthy fight.
- Real-time is still headlining our Web experience.
Twitter has certainly captured the real-time Web arena's attention in a big way, but PubSubHubbub-enabled feeds are also beginning to make their mark. Clients utilizing them receive pings immediately after a post has been published. This is golden compared to standard RSS feeds which, as you probably know, poll at defined intervals
