This guy has been keeping a tab on how fast the blogosphere is growing, it's about 2.8blogs/day... From what I understand it's only based on weblogs.com but it should be significant enough to show the trend...Jarrett House North : I thought this was a good time to make my source data available. I will continue to post comments as new high water marks are reached, but I think it will be more useful if people can get to the data themselves. It’s now downloadable in Excel format from this site. (The spreadsheet is under an Attribution-ShareAlike Creative Commons license. Feel free to use it wherever you like, just give me credit and make any changes and additional research available.)
