Am I missing something? Why would I use the site formerly known as del.icio.us (now delicious.com) to find information online instead of just doing a Google search? Let's do a little comparison.
I want to find the site for National Geographic so that's what I type into Delicious. I get a bunch of sites dealing with National Geographic, but the main page for the site is nowhere to be found. Since Delicious is supposed to be all about tags I click on a tag labeled "nationalgeographic", and am greeted with a bunch of seemingly random articles, etc. from National Geographic. Next, I click on the link to see the bookmarks sorted by popularity. Surely, the main National Geographic page would be the most popular and would appear first...right? Well, yes and no. After looking through the new list, I finally find the main page for National Geographic which is in fact the most popular. The only problem is that even though I am looking at the "popular bookmarks" they are still not sorted by popularity, so the entry I was looking for was 5th on the list. Now let's see what happens with Google.
I go to Google, type "National Geographic" into the search box, and the main National Geographic page is the first result. I click on it and I'm there.
Outside of work I do not see any benefit in looking at other people's bookmarks either. I clicked on the user that came up first for the National Geographic page, and I see that this person has 3332 tags. The majority of these tags don't have anything to with my original search or anything that I am interested in. The bookmark sharing seems to assume too much. A Delicious user and I both being interested in National Geographic does not mean that we have any other interests in common. The person I have the most in common with is my wife, but even she and I probably wouldn't have any bookmarks the other would want to look at. The delicious website says that "we can show you the most
popular bookmarks being saved right now across many areas of interest". I do not believe that a social network is better at deciding what I'm interested in than I am. When I'm online I want to see information that I'm interested in, not necessarily what everyone else thinks is currently interesting in that subject area.
I do see that with only looking at co-workers work related bookmarks, Delicious could be useful in sharing information at work, but I don't see myself using it at home.
On a side note... Did anyone else find it a bit strange that "vegan" was the #2 tag for JPL? Who knew that vegan(ism?) was so popular? Not that there's anything wrong with that.
