I have previously written about Microsummaries a feature introduced in Firefox 2.0.
I've been hoping that online bookmarking service del.icio.us would support Microsummaries, and now they do.
Or at least in a del.icio.us extension for Firefox. I have written about this extension in a post entitled "THE Firefox extension at the moment: Firefox and del.icio.us unite!".
When you have this extension installed, you simply press CTRL/CMD+D when you're at the page, you want to bookmark. Note that the name of the bookmark field is also a drop down box. So just click the button to expand the menu, and select the Microsummaries title.
It's illustrated here:
I'm not yet sure if the Microsummaries title shows up in the list at del.icio.us…
Update 1: After posting this and reloading my del.icio.us bookmarks it seems that del.icio.us don't support Microsummaries full yet, since it still has the "Ode to WordPress" title. :-(
