My University released a web based timetable system that was absolutely shocking - it was an ASP.net based site with the kind of unfriendly interface you expect from a 1990's era intranet site (hint: utterly utterly horrible, it produced one timetable PER MODULE rather than a single combined timetable and every time you selected a module it would refresh the page). I was hungover the day before term started and rather than use that system I hacked together an easier to use alternative from my bed using python + flask in literally 60 minutes and released it[1].
The administration went crazy when hundreds of students started using it and asked me to take it down. While its not as impressive as something made at Yale it seems to be a common theme, I wonder if other universities suffer the same issues. Could be a market opportunity.
