Sadly there was no response whatsoever from my Show HN, but LineUp has been profitable since launch (minus my time/effort), gains about 100 new users per day, and was recently featured at TwilioCon in the Community Hall. I'm currently working on the UI/UX and the next big push for users, but have a few other things, like my actual job, getting in the way.
I was initially afraid this app could take a turn for the worse and become used mostly for "less respectable" activities, but what I have actually seen are (in maybe 30% of total users) small businesses (like hair stylists, landscapers, and other one-person companies without a main office) looking for a cheap/easy way to not give out their personal phone number.
The other main use case I see (about 10% of total users) are international (non-US) users, presumably to make/receive calls with US-based people without incurring international or long-distance charges.
