Having used MediaWiki (the software that runs Wikipedia) extensively, I can vouch that there are usability issues that, if addressed, would greatly increase the ease of use, and the quality of editing, of the average user. Much of what is proposed by NEW! makes sense, and the end result would be an increase in participation and use of Wikipedia, as well as a reduction in server load (as edits would need to be tested and re-done less often through a WYSIWYG editor).
Kudos to NEW! for taking the time and energy to propose these changes, and hopefully the developers at MediaWiki take these suggestions to heart.
