What is a Permalink to a blog entry?
A Permalink is a unique URL assigned to each blog entry in your profile, and it never changes. When you click the Permalink option under an entry, a page opens displaying just that entry. If someone wants to link to one of your entries, all he or she has to do is click the Permalink, copy the URL, and use it as the value of their link. The link will always open the same entry unless you delete the entry.
