My heart sank as I read this post and looked at the product. This has everything going against it.
First: Online comments are a notorious anti-feature on many sites. You're basically making it so that they're instantaneous and impossible to filter. Major sites have to do an enormous amount of human reading/filtering just to have comment sections that aren't filled with horrific, violent, sexual imagery[1].
Second: This is a B2C product. If your customers are users, then your customer-acquisition costs are high. If your customers aren't users, then your customer-acquisition costs are still high, but your sky-high user-acquisition costs become fixed costs (you can no longer monetize your 1st user, but more like your 100,000th).
Third: Have you ever seen a live web chat on any site? These were popular in the late 90s as a drop-in feature that non-coders could use. They were absolutely full of filthy comments. I've seen chats that had 100+ messages per minute, and they were totally incomprehensible. That's even without any professional-level trolls involved.
Fourth: If you think this was a good idea because a business guy and marketing guy liked it, then you need to take a look at every failed business. There's almost always some sort of "expert" behind it. Even professional investors don't know if ideas are good or not; only customers do. What customer discovery have you done?
My strong advice is to work at least part-time. Don't go into debt for this. Get people to use it first, and then decide to put money into it. And if you can't get anyone to use it or invest in it, it's not because they "don't understand". It's because this wasn't a smart move.
I'm telling you all this as someone who's been there before. I've failed at exactly this kind of business. It took a long time before my delusions finally evaporated and I saw that all the people warning me were right. It's great to dream and be optimistic, but when you truly have a great business, people will give you money for it. If you don't get money soon (investors or clients), move on.
