Well, here's a better idea : create a service which let's me do that easily.
Not sure what the service would provide on top of that. Can you elucidate further?
I don't want to deal with opening a LinkedIn ad account and figuring it out.
I believe there is a service which allows you to search and find common interested with the person you're meeting, but this to me is more interesting.
If anyone wants to build this, feel free to ping me, would be happy to give feedback as well as sign up as a beta customer.
