We haven't quite been considering the latter folk for obvious reasons, but we have been pondering the general question of "which types of people should we index?"
I think this is an interesting question to consider.
One framework we've been using to try to answer this question is the old vitamins vs. painkillers line of thought. Where is the need for a product like this the greatest? Or "where is the consequence for missing out on a piece of content the highest?"
This line of thought leads us towards the finance folks, where a single piece of information/alpha from a thought/industry leader can lead to 100+x returns, and missing out on those returns can be financially painful.
But I'd love to hear others thoughts on this question.
