Perseus blog study shows the importance of choosing your sample

The Perseus blog survey that says two-thirds of blogs are inactive has gotten a lot of attention lately.

Cyberatlas does a good job of comparing Perseus’ study to The National Institute for Technology and Liberal Education (NITLE) Blog Census, which shows that two-thirds of blogs are active.

The big difference is that Perseus took the easy way out and only looked at hosted blogs, while NITLE took the trouble to gather a reasonable sample. It appears that NITLE has missed a lot of blogs that Perseus counted.

The two surveys’ blog counts are striking. NITLE measures 1.4 million and Perseus estimates that total is 4.1 million. In any event, the number of bloggers, active and otherwise, is in the millions.

There is some great information on the NITLE site that is worth checking out.
