The differences between the two are less obvious, but are interesting. By contrast, Suite 101 has no ads, and I've never seen it advertised anywhere else. All its contributors update their sites weekly. The number of links from a particular site in the directory isn't too variable. In Suite 101, some contributors write articles weekly, some do it every other week, and some do it monthly.
Some topics link to a lot of resources, and others to only a few.
I like both directories. Send comments to Aaron Taylor .
