    Vermiculite will float, not as much as perlite though. Be aware vermiculite breaks down and turns into a mushy substance. It's okay if you change your substrate annually but I wouldn't use it for much longer than a year. Perlite breaks down eventually too, but you're probably good for two or three years.

    Yep, a lot of growers don't use vermiculite do the factors previous members have already mentioned (minerals and mushyness) and it's really just not necessary. For example, Peter D'Amato switched his mixes from vermiculite to perlite, so if you're looking in The Savage Garden, some of that is outdated. Perlite's definitely better for the plants, I grow almost every plant I own in a mix somehow containing perlite, and I've never had any problems!
