These are short bits of information in bookmarks’ titles that update from time to time. Imagine bookmarking an eBay auction and seeing the current price in your bookmarks bar, or bookmarking your webmail and seeing your unread messages count, or bookmarking this blog and seeing the latest blog post title. Well with the last one, you can. Here’s how:
First, install Firefox 2.0 if you haven’t already. Bask in the integrated spellchecker, marvel at the extension upgrade process, yadda yadda yadda. Got it? OK.
Go to my blog and bookmark it by either going to the “Bookmarks” menu then “Bookmark This Page…” or using the Cmd-D keyboard shortcut (Ctrl-D on Windows/Linux).
Wait a couple seconds for the “Name:” field to become a dropdown. Finally, choose the one under “Live Titles” and your bookmark will update periodically whenever I make a new post.
Hopefully the Firefox team improves the usability of this feature, it’s kind of sad that there’s no way to spot microsummary-enabled sites out of the box. I suspect that extensions and Greasemonkey scripts will fill in some of the gap.
Also, I’m just scratching the surface of microsummaries. It’s even possible to add microsummaries for sites that don’t support them (including the eBay example from above), but now that you know about them you can go find out more on your own.
[Update: OK, the UI isn’t as awful as I thought, I originally thought the only way to get the Microsummary was to bookmark and then to right-click on it and choose properties. I’ve updated the post to reflect the fact that Microsummaries are also available with the “Bookmark this page…” dialog.]
