For format snobbery, my friend, you've certainly come to the right place. All of us are highly self-assured full-frame or larger shooters, you'll find not a single one of us shoots with a crop-frame DSLR. And you'd certainly expect such, since this is a place for people who produce excellent photographic work, and all of us have many spectacular FF images in the gallery, and we all know no one with a crop-format DSLR can produce anything worthwhile. You're among friends here.
But all kidding aside, what sub FF camera were you using? That's quite a broad grouping of different viewfinder sizes to be pigeonholing into one category... I find that, though I love the gigantic FF viewfinder of my OM film cameras (larger and brighter than any FF DSLR, as well), I find the tiny viewfinder on my old E-330 (2x crop) to be quite usable and the much larger (but still not FF) viewfinder of my Pentax K20D (second largest in the class, after D300) to be just the right size for most things. Easily large enough to manually focus and pick out minor details of the landscape, but small enough that you don't have to scan too much with your eyes, which can be important in some situations.
