"del.icio.us" was!
Thanks TJ, liked your article so much I stole it, and reposted here!
del.icio.us the web service that emerged some weeks ago has been quite a mystery for me. Then I discovered this Robin Good's article and started to think about it again. Initially I thought what another online bookmark service should bring. There were so many of them a couple of years back that burned their fingers. The only new thing should be interactivity?
An online bookmark storage would work like this - you upload you exported bookmarks a place them in a shared folder, where your friends/ colleagues could access the whole file if they want. Really who wants to see your bookmarks in such a time consuming way?
Delicious does it differently. First it's very simple. Also it stores single (not entire lists) bookmarks and ranks them by counting how many people have bookmarked it already. Additionally it uses a taxonomy to create helpful categories of all these bookmarks. In all it's a very flexible, fast kind of Open Directory. As of now there are nearly no spammers in it, making it a great tool for finding interesting non mainstream news.
Some weeks back I already drafted an article asking the audience here, who understands this tool. Now I get a decent amount of my noteworthy bookmarks every day from del.icio.us. Indeed, it is delicious :-)
