When someone else is trying to link to a specific story on your weblog, very few things are likely to frustrate that person as much as not being able to find a stable URL to the story in question.
My previous note explained how to set up a permanent anchor that cold be used in a link on another site to take the browser directly to your story.
However, creating the anchor doesn't do any good, because it doesn't tell other webmasters/webloggers what the anchor is. The anchor is there in the source, but nothing's been displayed on the page.
I would recommend using either an icon with an arrow indicating "link to me" (somehow) or a small line of text that says "Link to this story", or something else along those lines. Surround your text or image with the following:
<a href="<!--#archiveUrl-->#<!--#msgNum-->">[text or <img> here]</a>
Put that in your weblog's item template also, and you'll automatically generate exactly what other sites need to link to your stories.
