Just today Technorati pushed a new redesign live. Amongst other changes, it now uses jQuery as its primary Javascript code base. This is huge news as another big web site chooses jQuery as their Javascript library of choice.
If I had to guess, as to why they chose it, I’d say that they appreciated the bandwidth savings that jQuery afforded them, while still providing a number of useful usability improvements. I’ll see if I can’t hunt down who was in charge of the Javascript for the redesign to get their actual thoughts.
