I never used to use them before, now its kinda of lonely and quiet when they arnt around complaining to you or commenting on the weather.
That is exactly why I do *not* want companions. One of my favorite things about TES series is that sense of isolation and total freedom from being dropped into an open world all alone... where you can go anywhere without worrying about anyone. Nobody would miss you if, instead of closing shut Oblivion gates, you went off into the wilderness and lived in a cave. I don't want some party of followers tagging along! If I want to talk to people, I'll go into a town. If I want to do quests I will, I don't want companions steering my RPG experience.
I don't mind the occasional quest-related companion but apart from that, I prefer to adventure alone, and TES isn't really geared towards parties of adventurers.
See, this I can make my peace with. If, for a certain quest or another, I need a temporary companion, that's ok. Escorting/rescuing people is an established tradition in TES. But, as dikeybird747 says, TES isn't about followers or group dynamics. If you want that, go play Dragon Age.
