Einen interessanten Ansatz, Themenverläufe bzw. Themen an sich dynamisch zu visualisieren, verfolgen Ben Vershbow und if:book für eine neue Website über ein Buch:
> The other half of the site will be a discussion forum set up in [phpBB]. […] The gateway to each forum will be a two-dimensional topic graph where forum threads float in an x-y matrix. Their position in the graph will be determined by the time they were posted and the number of comments they’ve accumulated so far. Thus, hot topics will rise toward the top while simultaneously being dragged to the left (and eventually off the chart) by the progression of time.
