HN seems to still be pushing the post to viewers since I have some comments on the post (thanks sanity3141 and cloudking!) and upvotes (thanks random strangers!). But I think the lack of a website is the major turnoff. I initially thought that the allure of the title would be enough; clearly I was wrong :D
Even if the site immediately starts a video call when you open it (like Omegle) you'd probably get a lot of people disconnecting immediately and generally wasting your time.
Personally I'd be more interested in a large group chat you can just hop in and out of, less social pressure that way, and easier to keep going.
While a very small sample size, even those who did end up joining weren't interested in having a chat. So it might be the case that this isn't as needed as much as I thought it would be.
On the flip side, I'm glad I didn't put that much effort into it. I had some friends who suggested a much more sophisticated bot.
