Well I generally rely on my courier to give me a letter telling me the location of my next shout, since I killed parthuunax and the greybeards wont speak to me.
The courier has ALWAYS arrived a day after I find the shout with a new locale; but he has stopped. I haven't found all the shouts either!
The courier comes from a completely different trigger. I'm not sure what specifically, but it's something linked to people witnessing your shout. With some random factor thrown in, it seems. You've just been really lucky so far.
shout around people in cities to trigger the courier. this may take several shouts. you can not receive another letter until the current one is completed. also I always discard the letter as soon as its done. do I don't know if that is a factor.
I've had loads and then they suddenly stopped. After the patch however they've started coming again. Maybe it's a broken trigger. At lvl 41 I have all the shouts and 9 of them complete, and that was helped massively by those couriers
Tip to getting them, When getting around a city, travel using Whirlwind Sprint. I get told off by the guards about 4-5 times an hour.. im so glad they dont remember they told me off, must get me mixed up with all the other Dragonborn
Had two visits from the courier yesterday, the second was in the middle of a blizzard in Dawnstar and he met me on the beach in his underwear. I have no idea what that was about!?!?!

just shout in a bar, go out and he will come immediatly when your back in the city.
And here my little goodie two shoes has always been careful not to shout around cities so he doesn't make anyone upset ... and I lose out on a courier?
