Sufficient density. It used to be that you could know pretty much everything about computers, but not any more -- not by a long shot. (The same could be said of mathematics, physics, or several other fields.) In the IT business, you really have to pick and choose what you learn. There's always a buzz of new ideas, which is what makes it such a fun field, but which ideas are worthwhile, and which are a waste of time? Some people just seem to try out everything that sounds cool, and revel in that approach. Not me. I have to wait until I hear a thing mentioned in enough places before my interest is piqued.

Which is a long way of explaining that I've set up a list of my favorite links on del.icio.us. I'm a little dubious that a site for publicly listing your favorite links will have the broad social implications that some people are predicting for it. But, it's reached sufficient density to at least appear on my radar. And at least I'll get to access my hot links from anywhere. So what, beeg deal.
