Ask HN: Which project should I focus on?

There are 2 projects that seem very useful and something I really enjoy, but I'm not sure which one to pursue. I would like to get your opinion on it. To be totally honest and clear, I have no budget for either of those projects. I am willing to put my time into them and to be patient even if it takes years.

1. Gay adult project

I am gay and have pinpointed what bothers us in the gay community and what can be improved. It is a gay hookup site but with a significant major improvement. I think that could really improve the hookup scene in the gay community. I have no business model or way to monetize it at this moment. it is a location-based so kinda hard to market because I have to promote it city by city. I do have some adult followers on my Twitter and I started to write the blog. Here I know exactly who to target and who needs this service. Just not sure how to target those people, but I have some ideas.

2. Mainstream project

This is a mainstream project with a clear business model and earning plan. It is not location-based, everybody can jump in and participate. One side pays while the other side gets paid. Here I don't know how to target an audience, I have some ideas. This one is either "it goes viral or it doesn't". I don't really know if people need this or not, but I know that people want to earn money, while other people want to pay someone to do something or to see someone do something. This project is technically well-defined, but business-wise not so much, the purpose is not really clear for me.

If I may, I could share landing page of each project so you could get a better idea about what it is, my description here could be vague I'm not here to talk about the features of each project or competitors, I'm here to get advice on which one I should pursue.
