Here is a post from Terry Frazier's weblog: The Power of Knowledge Sharing.  The part about 90% of the corporate knowledge being in people's heads has to be close, even if it's a bit exagerated.

I noticed the grave need for knowledge management and preservation in late 1996.  I worked as an intern at a software company fixing bugs.  A friend of mine from the college also started at the same time.  I had one distinct disadvantage: he was a morning person, and I wasn't.  So he was able to track down our manager and ask all kinds of questions in the morning.  I worked in the afternoon and seldom saw him to pick up all of the great answers.  When I asked any repeat questions, my queries were met with an exasperated expression on the face of someone who was already overworked.  "It's not my fault!", I thought.  "You should write some of this stuff down in a database so I can look there first.  If it's not there, then I will ask you."

So the need became apparent.  There ought to be a way for someone to leave notes about questions answered and problems solved so someone else could search it later.  Imagine that!  I didn't know then that the concept fit into a broader knowledge domain called "knowledge management" (often abbreviated as "KM").

Evidently there is a technique in which a small piece of Javascript is embedded in a hyperlink on a webpage.  The hyperlink can be dragged onto the toolbar of the browser and executed later.

The cool thing is that the bookmarklet has access to the HTML DOM of the document currently in the browser and can modify or read the contents of the document.  The hyperlink Javascript does not have to be huge.  It can append the current document's DOM with a reference to a script stored on a server that can be much longer and more sophisticated.

I've wanted a way to blog pages I find without always needing to type up all of the stuff that goes around it.  This way I could grab the page title, address, and maybe some metadata as well.  Or how about harvesting the hyperlinks on someone's blog to analyze the intersection with others'?  You could almost begin to draw some conclusions about interests and community based on who links to who.  (Not that I'm smart enough to pull code like that off.  I've never studied AI algorithms, so I'd be reinventing the square wheel, I'm sure.)

Jon Udell gives a great example of a bookmarklet that allows him to request books that he finds on Amazon from his local library.  Now that's integration!  The concept of an agent connecting two diverse entities is called an intermediary.

Not sure how to react on this one.  I smiled and snickered at least.  More power to him I guess.  God loves everyone, even Elvis.
