I think the biggest flaw with the current layout of the Tool pages is that on any Tool page the discussion happens aaaaaall the way at the bottom. But, it's a layout challenge because how on earth are we can't just put it at the top and the Wiki at the bottom? That also doesn't make sense to me (but I might be convinced otherwise if anyone has any good ideas on why that should be done). One option might be a "Table of contents" block that has links to jump to "Tool profile", "Tool Wiki", and "Tool Forum" and perhaps the block follows the user as they scroll up and down on a tool page.
