Well, I'm always open to correction, serious or otherwise...

For myself, I'd prefer "use" to "utiliz/se" (and I do prefer the apparently incorrect "ise" to "ize" and will go on using it, simply because it's what I grew up with and I'm comfortable with it). I had no idea, though, that "employ" had ever been restricted to units of human resource, so I've learned something today. Thanks!
