Wow... this is a pretty impressive mod! Characters about town, in the wilderness, and recruitable NPCs with actual personalities, instead of all the bland stuff the game shipped with. I'd have liked to see more of the NPC interaction it adds in the base game, too. Pretty cool!
It is really, really good.
Even the wife I married this time actually has more to say than making food or how she opened a shop. There was actually a date (just one though, which is still pretty weird), actual marriage things, and actual conversation.
I went on a quest to exterminate vampires only to find an Argonian vampire hunter examining their corpses. I ran into the Dwarvenborn, the one who will stop the Dwarven world eater. I met a conjurer who only became a conjurer because he was too lazy to carry his own weapons around. I listened to Qa'dojo try to talk up a tavern wench. I came across an old woman who was travelling Skyrim because it was the only place her son didn't manage to visit before he died. I met a merchant who only wanted to buy and sell junk like spoons and forks, because he would sell them at a profit to other merchants. I listened to the two racist thanes in Winterhold tell funny racist jokes until they told one about Redguards, at which point I slaughtered them.
The effect is even better when you add it with mods that just add misc normal people that don't have anything to say. Like populated taverns that put in patrons depending on the time of day and how large the city, as well as mods that just add more random people to cities. Then you get mods that add in named characters but don't have anything to say to you, and you'll always get surprised when you run into the occasional gem that Interesting NPCs puts in.
