So at the PubSub party last night, I chatted with Bob and Salim about what's going on there.
First of all, they are monitoring 6.5 million blogs and seeing 600,000 posts a day. That's pretty amazing. However, many of the 6.5 million blogs have feeds that haven't pinged them or updated in some time, so they prefer the more conservative 3,606,000 active blogs as the number they actually monitor day-to-day.
They've also changed the interface, making it far easier for users to see that PubSub is really about defining a search for subscribing in my aggregator (those searches can actually include several searches, for example: napsterization.org/stories -- to get all instances of someone linking to me, combined with "mary hodder" and "napsterization" to get all instances of the keyword use in posts, and then being able to define interesting subsets of the blogosphere.. so that I only get posts say, in the 40% to 80% conversational middle of blogs as they are ranked by inbound links... and on and on...).
PubSub does something interesting that the other blog services don't do... which is that they don't collect the data and store it... instead they match the data to the subscription searches and other things they collect and monitor, and then toss it. So they don't have to worry about structuring it in a database for later. It's an interesting premise, this idea of not searching historically but rather searching just what comes through, which they call "prospective search."
Nice work guys.Posted by Mary Hodder at November 19, 2004 07:25 AM | TrackBack
