Clips blog @ Bloglines
"Clips blog" speaks for itself: just raw links to things that seem interesting in my RSS feeds. (Suffice it so say, that after a brief dalliance with Google Reader, I'm still using Bloglines.)
Del.icio.us is a service that many readers will likely be familiar with, though probably not everyone. It's also a kind of 'clippings' mechanism, though the idea is you store your favorites with tagged (keyword) references. Some people (Kerim) even use it as a way of housing an extended blogroll.
It might seem redundant to have semantic tagging when you can basically find anything you can think of with simple searches in Google or Yahoo. But del.icio.us seems to be most surprising when you're trying to find things that relate to what you're interested in, but that you wouldn't necessarily know to search for. The people who seem to have adopted it first are techies -- many software people seem to use del.icio.us to keep track of links to "helpful hints to debugging in DOT.NET" or "quick Linux hacks" (see Popular). But there's no reason why people interested in literature, art, and politics, can't also be using the service to connect to each other, and to find out about things via keywords.
Incidentally, the process of posting to del.icio.us becomes pretty easy with their handy Firefox extension. Once you've installed the extension, it just takes one click to add a post.
I'm still not 100% sure whether del.icio.us tags will really be a big-time revolution -- "the next phase of the internet" -- or simply a service that appeals to hard-core users (bloggers and the like). Del.icio.us is certainly growing fast, and especially so since they were acquired by Yahoo!, but their interface isn't exactly fun.
The title of this post might be somewhat misleading, since obviously I'm not suggesting that semantic tagging services like del.icio.us or Flickr are somehow going to make conventional search engines obsolete. At most, the two forms of accessing resources on the web will be complementary to each other. But there is an additional level of interactivity involved with tagging -- you leave a trail across the net (if you want to), which either you yourself or someone else could possibly make use of later.
Finally, a word on CiteULike. This is an academic-oriented service, that allows you to bookmark articles you've read online, including those that are behind university subscription databases -- such as Project Muse, JSTOR, EBSCOhost, etc.
I've just started playing around with CiteULike, and I'm not quite sure yet whether I'll be using it regularly. It might be a useful tool to get into a better discipline with regards to actually reading journal articles (instead of just doing searches when I'm working on an article or a book chapter). Like Del.icio.us, CiteULike allows you to share links to articles and view other people's articles, making it potentially easier to keep up with other people who might be doing research that relates to yours. And the "notes" function allows you to read people's thoughts on the articles they're reading. As with Del.icio.us, this service will only be of great value as a relational index if a large number of people in a given field are actually using the service regularly.
Again, I get the feeling that people in the sciences are using this extensively, while humanities folks have barely touched it.
Any thoughts on these services? And what do you think about Tagging vs. Search? Are there other tagging services you would recommend?
