Export blog entries from Blogger

This is an HTML feature. You can either use the <acronym> tag, or a <span> element. If it's not an acronym, I'd recommend using <span> with a custom class attribute. The trick is to place the text you want to appear in the hint as the title attribute.

Here's an example of the HTML:

Can I get this <span class="myclass" title="as soon as possible">ASAP</span>?

Now to get it formatted with an underline, you need to add this style anywhere in your HTML, preferably only once in your template:

<style type="text/css">
  .myclass {
    border-bottom-width: 1px;
    border-bottom-style​: dashed;
  }​
</style>

This should work in all of the major browsers.

Run a search for "RSS" in the Apps section of Facebook.

You'll come across some such as RSS Graffiti, Simple RSS Tab, etc.

If you install them on your profile you should be able to hook them up to the RSS feed of your blog and have it republished or syndicated on your wall.
