Just a quick thought on tagging. With all the social software and community, as well as blogging and other services embedding tagging, i wonder if the net effect may be a mainstreaming at the expense of granularity. I noticed that I often tag up sites on delicious with the most obvvious, common, and recommended tags. And i bother less now than i used to to create new ones, or to use specific ones. In part because I dont want something to get looked over, so my laziness results in a lazy contribution. Just a thought. It would be a pity if tagging cultures left behind a bunch of interesting but overlooked isolates; isolates being sites that are interesting but just never got the traction.
