You might want to be more specific about what you are looking for.

A technical person? A business person? Someone to help raise funds? Something else?

I'd also suggest looking for someone who wants to do a small project with you around talkfi, maybe for $$, or a slim slim bit of equity. That lets you get to know a possible co-founder (like dating) before becoming true partners (like marriage).

Here's my advice for finding a technical co-founder, but you can probably flip it around if you are looking for a different type of founder: https://www.mooreds.com/wordpress/archives/3445

Also, put contact info in your account profile, otherwise it looks like you are just advertising your product or are new to HN.

Good luck!
