Recently, Perseus Development Corp. released a survey they conducted of 3,634 randomly selected blogs on eight leading blog-hosting websites: Xanga, LiveJournal, Pitas, Weblogger, BlogSpot, Diaryland, Blog-City and TypePad. The main conclusions drawn from the survey were:

• There are about 4.12 million blogs that have been created using one of the services as of October 2003, and Perseus predicts based on their data that there would be more than 5 million by the end of 2003 and more than 10 million at the end of 2004, as evidenced by the following graph.






• Abandonment rates for blogs are high—66% of surveyed blogs had not been updated in two or more months. A little over a million were just one-day wonders.



• About 80% of blogs had external links, although they rarely linked to traditional news sources.



• Active blogs are updated much less frequently than expected—only about once every 14 days.
  • About 100,000 blogs were updated at least once a week.
  
  
  • Less than 50,000 blogs were updated daily.


• Blogging is a trend for the younger generations, as over 90% of bloggers are under the age of 30.
