From a usability standpoint, well any standpoint for that matter, treating links as if they were footnotes makes absolutely no sense. It defeats the whole point.
The website for the Chicago Recycling Coalition uses this approach in full force:
Dates and locations for collections in the Chicago area can be found on the IEPA website link, under “web resources,” below. – ChicagoRecycling.org
It was hard enough finding that tiny bit of info on their website, let alone then having to sort through a list of links at the bottom of the page to find the collection dates. What could reasoning for not placing the link right there baffles me.
Making your website visitors work harder than they have to is moronic.
