Hungry for some del.icio.us chow!

Ok, I enjoyed the video. The term "peer driven information directories" struck a chord - that's pretty much what we've been covering these last weeks and it's interesting to see an "official" term for it. I also liked the term "folksonomy".
I feel pretty much comfortable with computers - I have fond memories of writing my own programs in Basic, being the only teen in the adult computer club in the Canal Zone, and loving my Atari 130XE. I have great memories of discovering Mosaic while an undergrad... and spending my alloted "allowance" on pictures of David Duchovny. Ahh, what a great use of my printing allowance (good thing I wasn't a business major). So, I feel like I know more than the average user... that is the average user over the age of 18.
I go on again about the social networking aspect. I admit, I'm not a social person (at least in my private life). I wasn't sure why I would want to use del.icio.us. Ok, I do like the idea of my bookmarks being available anywhere I enter the internet. So that's cool. And it reminds me of StumbleUpon, a website that lets you rate websites and finds new ones for you. But StumbleUpon automatically assigns the tag/s for you, so that's not too helpful. However, if you use Stumble to find the website and del.icio.us to bookmark it... that sounds like a happy marriage. It is interesting to see what others have used as tags... but I find myself getting annoyed with some of the choices. It's an individual thing, of course, so it need only make sense to the initial user.
Another thing mentioned in the video was about following copyright: does anyone follow copyright anymore? It falls under the professional ethics of librarians but I know plenty who don't follow it. I'm wondering what kind of copyright laws are involved with posting links to other websites from your own blog count as. If you're just talking about how wonderful a site is (see my links within posts for instance), are you obligated to get permission to link someone's website? Where does the line get drawn? Are we moving away entirely from copyright law - it seems almost impossible to be able to police? And why would you have to worry about copyrighting in del.icio.us?
