The market share of US visits to Bloglines was 3 times greater than Rojo, its nearest competitive web-based feed reader. The chart below shows the traffic trend over the past year for the leading web-based feed readers. You can see that Google Reader has grown lately, but as of the week ending 1/13/07, it had only 1/13 of the market share of visits of Bloglines.
TechCrunch's post about the Hitwise data focuses primarily on Google Reader which is still getting crushed by Bloglines. But the more significant finding of the Hitwise post is not that Bloglines is still the dominant web-based feed reader but that a few popular blogs like Perez Hilton, Huffington Post and Engadget receive more traffic than the entire Bloglines website. As Hitwise's LeeAnn Prescott writes
this data suggests that "the most successful blogs are being consumed in the standard Web 1.0 fashion - by visiting the websites."
