I’ve had Feedburner on the mind recently (my last post was on the company as well). I’m on my way back from our first post investment board meeting in Chicago as I type this and I had a chance to spend yesterday afternoon playing around with their system (read: see how many hits and how many subscribers are being served to various sites that have burned their feed). Lots of interesting data there. Feedburner is preparing a post on this, so I won’t steal their thunder, but I will share three data points that struck me: First, the number of subscribers to the largest feeds is pretty amazing – the top sites have literally hundreds of thousands of subscribers. Second, the growth of podcasts is pretty amazing – there were no podcasts in the top 15 a few months ago; now there are several. Finally, there are now few porn blogs that are starting to climb the list (I guess that was to be expected, although I was hoping the feed world would stay a little more pure than that). Interestingly based on their hits vs. subscriber ratios, it appears that these sites are having their contentscraped a lot vs. actually having subscribers to their feeds.
I’ll post a link to the Feedburner post when it goes up – it will be full of interesting data on the growth and popularity of feeds.
