OTOH, I don't like the way threads are laid out fundamentally, which is that there is one table, and each node (of any depth) gets a row (technically, a pair of rows), and the content within those rows is indented depending on depth (achieved via nesting of <ul> elements, of all things!). I personally believe it would be better — more general and more stylable — to have actual page elements (<div>s, perhaps), one node per element, nested exactly according to the hierarchy of the thread. I think I have a patch for that around here somewhere...
