Some people don't seem to like it. I'm personally not a big fan of running from Markarth to Riften

I don't like fast travel. Doing it myself feels like some kind of cheating, like using a teleporter that doesn't even exist ingame. I didn't fast travel in Oblivion, or Fallout 3. In F3 it helped me discover lots of places, even start some nice quests, that else I wouldn't have discovered.
I respect whatever others do in their game, as long as their respect my decission. When I play this game it's like I enter some kind of virtual world, that I basically joined to enjoy and "live in", so I have fun doing it as real as I can, and want. I have my limits of course as I'm not a hardcoe (neither experienced) RPer. When I have to return back from doing a quest, it doesn't frustrate me to walk 30, or even 60 minutes, because I don't have any hurry to deliver the quest. If I don't have time that same day, I can finish my quest another day. I enjoy both the traveling / exploring, and the quest itself, so no hurries here.
