The problem is that almost every quest, besdies the MQ OFC, has anywhere from 5-10 possible locations it could be at.
To reintroduce the directions system they want would invovle having the voice actions re-record the same line upwards of 10 times, which is both something that is totaly unessessary and takes up a lot of space on the disk leaving less room for more things.
Also no I dont think I could ever change his mind and I doubt he belives he can change mine or anyone elses. All arguments on the internet are pointless becuase the likelyhood of changing someones mind is nearly zero, however without them internet forums would be dead and very boring places to visit.

The majority of the quests (all the 'good ones') aren't radiant. I don't do those 'kill bandit chief at X' or 'fetch staff from Y' quests. So for all the actual quests and even a great deal of misc. quests they could improve the description.
And even the radiant quests could have a better explanation written down. It doesn't need to be recorded but they could explain who needs the staff and why. It would just add a little bit more personality to the quests.
EXAMPLE:
http://www.uesp.net/wiki/Skyrim:Miscellaneous_Quests This is the list of misc.quests and as you can see not all are radiant
http://www.uesp.net/wiki/Skyrim:Delivery_(Hillevi) Here is a misc. fetch quests and you can see its description as well. The quest description could have included the
reason as to why it is important to deliver this item as well as
where the receiver lives. Even if this is radiant information than the radiant description could still include the
location. Like: palace, second floor. So even radiant quests could have better descriptions.
