linking

I was suprised at how easy it was to link to other sites or files on the website. As for the blog I forgot but was able to easily type in for help in the blogger site and it showed me the correct icon to click on for the linking.
It is said that linking helps build credibility to your site, be it a blog or a regular website. It shows that you are not just typing mindlessly and hoping that people believe it or follow it (although you might be anyway).
Wikipedia talks about what a hyperlink is and how it behaves. It speaks of html and also of the anchors. It has a little history about Ted Nelson and the coining of the term 'hyperlink' in 1965. It also talks about the legal issues surrounding the idea of the linking to cross reference.
I understand all of that text but it doesn't excite me. But I am proud to know how to use it.
