Why those people who want to have outbound links on their site is because they consider those outbound links much more important and valuable than the page contents they write. Having said so, to avoid wasting our valuable time to read those less important and valuable things from a web page, we can simply mask those page contents and only retrieve those important and valuable things that we want to focus to see and know. Here is an example that those plain text contents are being masked and that those important and valuable outbound links just show up. Such a technique I call it "Plain Text Masker". Is it interesting and fun? You can try to do it yourself.
