I know on Twitters search you put in a search word to find other people who are supposedly interested in the same niche but what I'm getting is tons of bullshit. For example, let's say I want to promote adult dating. If I put "adult" in the search or "adult dating" or whatever, all I'm getting is results of people who have used those keywords in the tweets. I could get granny in Florida who has a tweet about her adult grandkids visiting. How do we search for people that are really interested in our particular niche?
