Help me friends, you're my only hope!

Does anyone know how to do the Blogger version of an LJ cut who can tell me in a way I understand? Because I definitely do not understand the Blogger help page. I used to have several posts cut with the "read more" link and when I went back to see how they'd been done (Pat did them, that's why I didn't already know how they'd been done; he did them because, as I said, I definitely do not understand the Blogger help page.), I saw that those posts were all now expanded with a useless "read more" link at the bottom. Ugh. Help me! Please!

The Evolution of Language

I've always been interested by uses of words, like Band-Aid, Kleenex, and Xerox, where the brand name has come to represent the thing, regardless of the actual brand being used. If this kind of thing interests you, then it's especially fascinating to live in our times, where Googling not only exists, but the world "Googling" also exists. So, imagine my delight in coming across this Web site on the wiki for my social software class. When I was born, blogs didn't exist (nor did wikis or online grad school programs, either) and now, here we are 27 years later with an entire language used to discuss them. Crazy.
