I use the word perhaps every three or four months. I don't know what it's supposed to mean or where I picked it up at - though I think it must have been hanging out with other computerists. I get the same sense of "stickiness" that others report, but also the notion of attractiveness - like electrical or gravitational. Oddly, at the moment I can't think of exactly HOW I use it, but I'm pretty sure I've never used it to mean "understand."

It's one of those words on which I latch when I'm groping for a more discriptive term and think, "Well, this pretty much conveys what I intend."
