I've started a couple of Twitter accounts with the intent of tweeting out cool facts about specific niches on a regular basis. One is a sci-fi niche and the other is a US military niche. They're looking promising. I'm new to this so I apologize if this is a poor question but does anyone have any advice as has to eventually make money off of accounts like these? Are there any specific websites that I should look into? Should I start my own blog to link to?
