Myself, while I have certain shop preferences, say Summerville for the en-suite rooms, I follow the ML's, not really shops. I enjoy repeats, not having to start from zero, so will ask for her contact if she has potential. Makes it easy to find her (no whining "Anyone know where [....] is?") when I'm BOTG.

To answer your question, I'd say it's a bell curve, a few unknown shops, more smaller but known shops, then a few major shops.
