Technorati launched a significant update yesterday. While I'll let others discuss the merits (or lack thereof) of the new design, I'd like to lament the new scoring that Technorati offers bloggers. Previously, there was a ranking score which produced a number from 1 (the highest) to <unbounded> the lowest (or, effectively, unranked). With that form of metric, you could look at the number and get an idea as to where you were and track any changes you were making. With the new 'authority' score, we have a range from <unbounded> (the highest) to 0 (the lowest). Consequently, you can no longer look at your score and figure out where you are in the grand scheme of things. You would have to at least know the highest score.
This, to me, is a poor design of metric.
Interestingly, as the comments on the TechCrunch post indicate, reaction to the ticker at the top of the page has been somewhat mixed or negative. If you look at them closely, you will see that it isn't a real time stream of terms, but a cycle of terms repeated over and over (refreshed at some point I assume). In other words, the ticker nature of it is a presentation decision, not necessitated by the fact that it is (could have been) a real time stream of data.
In the big picture, I think the new design is an overall improvement, and the search speeds to appear to have improved.
