According to a report at ClickZ.com, the phenomena called weblogging is growing exponentially. The current number of blogs is now over 8 times bigger than the 500,000 blogs measured in June, 2003.

Technorati has tracked 3 million blogs as of the first week of July, and has added over 1 million blogs to its stable since then. Meanwhile, Pew Internet & American Life reports a new weblog is created every 5.8 seconds. That roughly translates into 15,000 new blogs every day. However, only a fraction of these are being updated routinely, less than 1 million in fact.

11 percent (approximately 50 million) of Internet users are regular blog readers. Active bloggers, meanwhile, update their blogs regularly, to the tune of more than 275,000 posts daily, or about 11,000 updates an hour.

Finally, the demographics of blog authorship are somewhat disputed, but the bulk of bloggers clearly are within the under-30 demographic. According to a Perseus study, over 90 percent of blogs are authored by people between the ages of 13 and 29, with 51.5 percent between the ages of 13 and 19.
