Aza’s Thoughts » Vote! How to Detect the Social Sites Your Visitors Use

by 5 others
How does SocialHistory.js know? By using a cute information leak introduced by CSS. The browser colors visited links differently than non-visited links. All you have to do is load up a whole bunch of URLs for the most popular social bookmarking sites in an iframe and see which of those links are purple and which are blue. It’s not perfect (which, from a privacy perspective, is at least a little comforting) but it does get you 80% of the way there. The best/worst part is that this information leak probably won’t be plugged because it’s a fundamental feature of the browser.

del.icio.us: usability lab

by 3 others, 1 comment
As mentioned here before, the del.icio.us team is presently in the midst of a major project: building a new platform which will speed up the site and help us grow even faster. At the same time we’re also taking a close look at our UI and exploring ways to make it both easier to use and more functional. Over the years we’ve heard a lot of feedback, both positive and negative. Many folks like the simple and terse nature of the site, while others take issue with certain elements of the design (shockingly, some of you think that light-blue-on-salmon-pink is not a good color combination; more shockingly, some of you think that it is). Our challenge then is to make del.icio.us better without messing up the stuff that already works.
