All things considered I think fast traveling makes getting places easier and faster. I don't have mods to populate the roads, and the habit of fast travel was developed playing the game originally on the Xbox 360 where traveling by foot was boring as all get out.
I'm currently working on just a regular playthrough with commentary on my end and still working out the kinks for a potential roleplay playthrough. I feel like I might miss out on certain quests and such just because playing a character that can't metagame like I do (or look up stuff on the wiki when I don't know something) and that scares me a little >.>
I won't post anything about it here on Steemit, but I stream my current play of Skyrim at 9am CST and upload the videos to my YouTube the same night at 6pm so you can find those at the following links;
