This is another one I'll have to live with awhile before I figure out its everyday impact for better or worse.
And, as with the blogs, I already have a system in place that works very well and is more colorful. On my hard drive I have several nested HTML pages of links on various topics. The arrangement is such that the links are easier to find (IMHO) than browser bookmarks.
So this feels sort of like re-doing the same work. However, having it online can be useful when I want to blow off time by surfing at work. (Just kidding!) On the other hand, it brings up another of those privacy issues. Like a list of books one reads, a list of websites one likes gives strangers clues to one's personality. But holding back on true favorite sites would make the list less useful to onesself. And making the list private would also limit it's usefulness; logging in every time would be a royal pain. So, o.k., here goes -- hey, world, I'm one mega nerd!
One minor complaint: sites that aren't shared by at least two people don't show up in a search. Yes, I know that's still a very low popularity threshhold, but one of the great strengths of the almost-infinite world of cyberspace is the "Long Tail." I don't want to know about some site that everybody else knows about. I want to find a site so esoteric that only one person has discovered it.
The main complaint is that tags are separated by spaces rather than commas, which means they must be only one single word. I want to be able to tag by phrases. This inability is especially limiting (or rather, not limiting enough) when the tag is a proper name.
