Forums are repositories for large amounts of information. Being able to navigate, locate and consume that information easily and quickly should be a prime goal. I have a couple minor observations.
There is very little "graphic" representation of ideas or information in the current UI. The most notable "nit" that I find is having to locate threads I have participated in by looking for the text "Yours" in the subheading of threads.
There appears to be some sort of information being represented by the change in color of text of thread titles, but I can't figure out what. I believe it was similar or the same prior to AMASS?
In general, the brain processes large quantities of graphic information much faster than text.
