Leads: 'Rating' field

Leads: 'Rating' field

I'm curious, how are other users using the Rating field under Leads? The default list seems pretty vanilla. What are some other, more detailed ratings that other users are creating?

Some ideas I have are:
  • hot, warm, cold
  • on-hold (maybe this is better suited for Lead Status?)
  • organic (unsolicited), inorganic (solicited)
Also, what is the difference between 'Rating' and 'Lead Status'?

Thanks in advance,

Brian
