Just a minor patch to my style, further modifying it from the Digital Multiplex it's based on. The change was simple enough: flowing article text around the userpic instead of leaving a column of clear whitespace below it. Doing it entailed modifying three S2 layer functions and the stylesheet, and as an added bonus, eliminated a nested table.
One minor bug exists: If a post contains an <ol> or <ul> construct that overlaps the userpic, the flow of the list around the userpic is calculated from the beginning of the contents of each <li> entity, NOT from the bullet or number of the listitem, so the bullets/numbers end up drawn over the userpic. Does anyone stronger than I in the fu of CSS know how to fix this, short of the quick, dirty (and undesirable) kludge of expanding the right margin of the userpic?
