With four sites, one can be down and we still have enough for information comparisons. In some cases, we've listed more than four websites on a particular topic. For example, we might provide a few for younger readers and others for more advanced learners. We believe in life-long learning and encourage people of all ages to explore information. Our primary audience is students who need starting points for a particular project.
Some topics are more logical for a particular age group.
For example, younger people are generally more interested in bugs, while older students might be interested in architecture or buying a car. Middle schools students often study explorers, while younger students learn about life on a farm. Overall, we try to select sites that would be good starting points for anyone wanting to learn more about a topic. We pick topics based on three criteria. First, as life-long learners we like to find topics that are of interest to us.
