I built a social rss reader that ranks content based on how much you liked other content posted by the same feed or user: https://linklonk.com https://linklonk.com I haven't marketed it much except for a Show HN. I spent $20 on Google Adwords to see how effective it is. The result was a few clicks but no new signups. I'm curious how other folks in a similar situation have marketed their side project? What channels have you found useful?
