I completely disagree. This service targets people who peg a higher value to their time than $100 / hour and/or are too busy to take on other tasks. This is valuable for anyone that runs their own business or who has an actual dollar amount pegged to their time (a large portion of HN readership), not just members of the 1%.
E.g., cancelling a doctor's appointment takes 10 minutes. Even if you bill your time out at $50 / hour, you've now saved yourself the trouble of making a random phone call for 16 bucks and remain focused on what you're actually good at.
