Plus 1 to Lauren!
Hand raisers often don't actually complete an activity, even after reminding them that they had previously indicated interest. And I agree that having the option to report on engagement/program interest using those numbers can be helpful, depending on your objectives.
What you will want to avoid is the trap of indicating 2,000 advocates but then no one to do a reference call when asked, for example. So don't let your numbers come back to bite you down the line!
