I would rate this a "5" for what I look for in a relationship, but it's not necessarily one of the first things that comes to mind for most of the guys I know.
If you want a lasting relationship, the "'til death do us part" kind of commitment, then I'd hope that, if you're going to choose to be stuck with someone for the rest of your life, that you'd choose someone with a personality.
I don't understand why, but some couples DO prefer to keep their love life and their friends as two separate things. They want "their" friends, and they don't want to talk to their spouse or significant other. I just can't see why you'd want to spend time with someone you don't want to talk to. But, if that's your thing, go for it.
