Learning from the top bloggers
Bloglines users have access to a list of public subscribers for every blog they subscribe to. That’s what I’ve used to try to validate the theory I explained in my Bloggers’ Theory post. Just for fun.

If click on the “subscribers” link, you get a list of public subscribers for the blog and the date they first subscribed. That is a good sample of all feed subscribers - not perfect - but good enough to get broad trends on what’s going on with almost any blog. Let’s assume a strong correlation between total readers and public feed subscribers - and call this the “Reader Index”.
I took the five or six high-traffic, best blogs I read. TechCrunch (Mike Arrington), Let the good times roll (Guy Kawasaki), Ray Ozzie (Microsoft’s CTO) , John Battelle, Venture Blog (mostly David Hornik) and Seth Godin. Then I used Excel Pivoting capabilities to build a cumulative chart of public Bloglines readers, to see if I could find the pattern I earlier posted about:

The data is fascinating. Let’s start with TechCrunch first.

This blog is not even a year’s old and counts over 20,000 feed readers. Now look at how smooth the seeding phase looks like - this blog started slowly, then things started to accelerate around August ‘05 and now you can see very nice growth, very steady. By the way this is one of the best blogs on Web 2.0, highly recommended.

John Battelle’s has a similar pattern. Now Seth Godin. His blog started late 2003. Did you notice the slow start - the explonential growth phase, and what now seems to be slower growth? Very interesting, maybe we all want Seth to write another book.

In an earlier post I was talking about how strong communities provide almost instantaneous readers for a well known and popular character - take the VC community and compare Venture Blog:

With Guy Kawasaki, who started a new blog earlier this year. Very fast initial growth, quickly reaching a saturation point, within days.

This is even more clear looking at Microsoft’s new CTO, Ray Ozzie, who started blogging in November ‘05.
