I think that tables are overused, when people use tables to display the whole site, that is overkill. I think that as Chris said, tables should be used for showing tabulated data, but divs should be used for content. Another advantage is that with DIVs/CSS it is easier to change the layourt of the whole site, just by editing a css file.
On these forums, all the lists (forums, posts, members, search etc...) use tables in the right way, and so do the topics themselves but using a table for the Rate this Thread/Forum Jump thing is silly.
We should wait for Guido's opinion, he is the resident expert on website design afterall
P.S.
my website only uses DIVs, and I think it would be hard to do something like that in tables.
