The cost of this demand type is attention. People will keep paying attention because they are invested personally (or they believe other people are invested personally and they want access to the peoplemarket).
You can measure the elasticity by adding anything detracting from user experience (i.e. wasting your user's time when you could automate solutions (e.g. cragislist spam apartment listings you spend 20 hours sorting through manually) or speed up your site (e.g. social website slowness/downtime/high variance in page load times)). You've found some elastic jumps when users start leaving because you're wasting more and more of their time.
People only have so many minutes of focusable attention every day. It's precious and irreplaceable. Don't waste your user's limiting waking attention with errors, manual aggregations, confusions, slowness, or "oops this failed try again and it may work or it may not work and you'll have to try again and it still won't work."
