Summary

Just because you can link everywhere doesn't mean that you should. Pages with extraneous links are no more useful than linkless ones. Carefully check out each place to which you will link. Is it really useful to your readers? Does it provide something new or simply duplicate material your other links already lead to? Does it appear to be on a reliable server or on one that's often inaccessible or slow?

Your goal should not be to provide your readers with as many links as possible, but rather with a choice selection. And you know that you must check, update, and add to your links often. Do that, and your visitors will return often.
