As far as real, career-enhancing editorial or writing positions, you probably should be looking outside of Utah. I tried to stay, and went through the same thing you're going through. I didn't even get a good job on campus--I was (for about two weeks) the part-time supervisor of some office, the name of which escapes me, in the Smith Fieldhouse. I believe it was a library office for phys. ed. Not sure.
Anyway, my point is, that if you get an offer that you feel good about, even if it is in Idaho Falls, follow that feeling. I went home to Illinois and ended up editing a magazine in Chicago for a year and a half when I followed that feeling, and it really gave me the stability I needed to be ready for grad school.
My old roommate Sallyann lives up in Rigby and she says that the singles' scene in that area--she used to go down to IF regularly--is busy, but young and relatively uneducated. Of course it would be, with Ricks so close. But she loves it there, and it's home for her.
I'd go to IF and visit, if you haven't yet, and make sure it's a place you want to live (says the girl who accepted the Seattle job sight unseen). Be certain to weigh all your options--what do you want in a new place? Boston's got it all when it comes to a singles' scene that's intellectual, educated, and driven, and you're likely to find any kind of job that you want there. I've got friends in publishing and writing who can connect you to the right people to find a job.
But the thing is, with Boston, Chicago, New York, and D.C., and many big cities like them, you have to decide to move there, have a little in reserve, and be willing to temp for a month or two till you find the right job. I went to Boston for grad school and happened to find a connection at school who got me in touch with the right person at Houghton to get a job two months later, but I lived on a student loan those first couple months.
So, staying local, within the state or the next state over, will help you in job hunting in that you can go interview and check things out without having to move there first.
Personally, though, I say go for the big, scary move. That's the thing you should be doing at your age. Do it now while you're single and have the mobility you won't have later. Explore the places you've always wanted to go. So what if you fall flat on your butt? I did that several times myself, and I never had to give up and go home. You just dust yourself off and keep going, and you find that falling on your butt is exactly what prepared you for the next thing.
Oh, and some of Boston's hospitals have some great free healthcare for people living under a certain generous income, something like $35,000. I know from experience that being without insurance when you get really sick is really bad. I don't know how other cities do it--Chicago didn't have anything similar, I don't think, but I had insurance when I lived there. But Boston's hospitals and their related clinics are research and teaching hospitals (mine was affiliated with Harvard Med School), so they're well-funded.
Anyway, just my thoughts, taken from my own personal experience of having been in a similar position when I graduated. It was so wide open that I could go anywhere, and the choice really was mine--I even had spiritual confirmation of that. I could have stayed in Utah and it would have been fine, too. But I'm a much different person now than I might have been had I stayed in Utah, and so I'm really glad I left and explored.
