In the early days of the web and the start of the page rank notion links from other sites was the goal. Web rings sprang up like grass in spring and one could find a web ring for lopsided pine trees on the south side of the house. As this happened web users soon realized these networks weren't all that useful for finding information. At the same time the amount of information on the web was blossoming and users time became ever more scarce.
This is all a long way of starting to talk about what is happening here. The site purports to be building a listing of the "100 most prolific bloggers". The thing is the bar is set so very low (1000 posts) that most anybody who has blogged for any length of time would be in the list. Apparently no attention has been paid to the top bloggers. How many posts make up this blog? I'm not sure Dave Winer even knows but it is certainly one heck of a lot more than the 40,000 listed at the top of the aforementioned page.
The ultimate question is what does it matter? Is a prolific blogger somehow better than a non-prolific blogger? What does making more posts really represent? In many cases it represents a lot of pretty poor writing without anything of much interest being said. Most readers would rather have a few well written stories than volumes of the poorly researched and poorly written things that fill up some blogs when the goal is "how many times can I post today".
