Aww, thanks for saying that! Okay, I've futzed with this a bit, yay futzing, and this is what I currently have:

#user-fandoms .index {
box-shadow: none;
}

#user-fandoms ol.index {
padding-bottom: 1em;
text-align: justify;
}

#user-fandoms ol.group:before {
content: "» ";
}

#user-fandoms ol.index li {
display: inline;
margin-right: .5em;
line-height: 2.15em;
}

#user-fandoms ol#fandom_full_list {
display: block !important;
font-size: .9em;
}

#user-fandoms p.actions {
display: none;
}

This gets rid of the shadowy line inbetween, offsets the list of ~lesser fandoms from the Top 5 while making sure there's a bottom-padding when there are only five fandoms or less, and rescues a tiny bit of screen real estate through font size. And I added a raquo because I have to add raquos to everything. That one can obviously be taken out (and probably should).

This won't appeal to people who want to see the whole thing as a unified block, but I didn't like that the first <ol> was shorter than the block beneath and subtly stuck out. Now it sticks out MORE. :-D
