To make reddit work, you need to make sure of a few things. First, know the culture. Memes and talking points of the moment, what's generating buzz. Second, know the games you're submitting - what genres they belong to and what their strengths are compared to prominent titles. Third, don't use a dummy account, use your own if you have one... use an account that has a history and a voice. Just spamming submissions will not work.
