It has been a while since I talked about Diigo. One of the first and best Web bookmarking services, Delicious, was first bought by Yahoo!, then mismanaged, and finally sold to the YouTube founders. In 2010 I was looking for a solid replacement. It was a similar story like with Google Reader, it just happened a few years earlier.

Delicious was a great, simple tool that helped me to collect all findings on the Web in one database. It had some sharing options too, mostly people following your Delicious stream, but it wasn’t very modern or comprehensive. In the early days, around 2007 to 2009, Delicious always looked a little bit like Craigslist: crude and not well designed.

Diigo does all of this better. Its usability is well thought out and the service has been now around for long enough for me to say I can recommend it to anyone who is looking for a solid tool to store bookmarks, to highlight and collect information. This is already great for study, to do research and write papers. But one of Diigo’s best and probably most underestimated features is Groups. This is a powerful way to create a digest of findings, which are subscribed to like a newsletter. Breaking out of the old “these are my bookmarks” scheme, Diigo Groups allows you to create topic-based digests of information, to which its members can contribute. This has the potential to become a knowledge base, much along the lines of what I wanted to do in 2009 with Cloudleaves.

You can join the Core UX Diigo Group if you apply for it on Diigo. If you want to be sure you are being accepted in the group, just an email address does not cut it. You should have valuable bookmarks in your own Diigo profile too and you should be willing to actively participate and contribute to the group. An additional email explaining your intentions does not hurt, but it’s not obligatory. The goal is to create a small compendium of knowledge in a field that is rapidly growing and changing.

I am looking forward to new group members and to your all contributions!
