I talked about this on the forums of where I play, but I'm interested in what some other people think as well.

Do all that many people have NPCs that are closely associated with their characters (like family, friends and such)?

If you do, do you ever bring them 'on stage' so to speak and do they get any playing time?

I like using them myself to enhance storylines, and provide atmosphere to a place. For example, if a character of mine runs a tavern, I'll emit a couple regulars and a couple servers/waitresses that are often there. If my character's NPC friends need some time on stage I'll find ways to do it, especially if it makes the life for PCs more interesting.

Anyone else do this?
