I found this link while doing research for my Craigslist redesign project: http://uxmovement.com/resources/poll-results-users-want-speed-over-social-features/
The survey was said to have found that speed of loading (Visibility of system status), simple design (Aesthetic and minimalist design), fewer clicks (Flexibility and efficiency of use) and a preference for text searching and intuitive navigation (User control and freedom & Consistency and standards) were important traits in web applications. This said, I think we've all heard that before in Nielsen's Heuristics and Shneiderman's "Eight Golden Rules of Interface Design".
Social Features, like a Tweet or Facebook "Like" button, seem to take the backseat to the basic usability of the site, which once typed out, seems to be common sense. To me, Social Features are just the modern version of the web Stat Counter - popular circa 1993 (and hopefully gone the way of everyone having angelfire websites). Everyone wants them on their site with the assumption that they will drive more traffic or interest - not to say, this doesn't happen or isn't at least somewhat effective for sharing information.
While an interesting article, the first thing that strikes me is how poorly the visual design of the pie chart is, specifically on a UX topic website. The use of color for the pie slices is the first thing that sticks out as a terrible mistake – the range of colors are too close to be readable and the legend perhaps would have been better as tailed text boxes pointing to each section. Secondly, the chart may have served better as a bar graph enabling the user to read the information quickly.
