Talking of website design, this article http://websitehelpers.com/design/ is a gem. Especially the section F "Make it Easy to Find Stuff", points F1 and F2 in particular, are relevant to the discussion.
This site is like any one of dozens or so others, they all say the same basic thing.."This is what you have to avoid to make an easy to use site..." I have been using this site, "Vincent Flanders Web Pages that Suck" as a guide as to what not to do for as long as I can remember teaching it all. (Such ICT skills are not required in the secondary education system here so I no longer teach it.) The complaints are always the same, clutter and unclear layout, lack of "intuitive" progression, poorly designed links, complex processes to achieve a simple goal, all things basic Moodle is guilty of, and I am constantly astounded at the number of seriously inventive ways in which people make such a mess of their web sites. I still go there, just for a laugh some times.
