I've been watching with interest the race between different titles on the top-10 ladder on the PF Library mainpage. For no apparent reason, "moment of inertia" has finally elbowed its way to the top. It used to be quite exciting … shhh! sorry! electric field was going at the speed of light … but, for obvious reasons, momentum was also a front-runner, and shot forward towards the edge of the universe … friction presumably got carried along stuck to something else … then the edge of the universe stopped expanding … and pressure powered its way forward … escape velocity obviously will never quite reach the edge of the universe … but time dilation may be able to overtake the others at warp speed … however, moment of inertia is purely rotational, so how did that make any progress: is there some velocity-spin linkage we don't yet know about? I find it difficult to believe that, in Peoria, "they talk about little else" Or that "moment of inertia" is coming up a lot in autolinking. My guess is that members and guests are looking only or mainly at the top-10 and most-recent-10 titles, simply because they don't see any others … once a title is in the top-10 list, it tends to keep others out and more importantly, the work done by members in creating new titles is little appreciated once their titles have left the most-recent-10 list. Could there be a link (perhaps just saying more) to (say) the top 100 viewed, so that members and guests can "shop around", instead of following the tourist trail?
