Absolutely! On Reddit, it is recommended practice to NOT engage in self-promotion while you are there and instead focus on providing a great deal of value to the community. Redditors are tech-savvy individuals who dislike it when members of their communities post irrelevant or irrelevantly related content. Put more emphasis on your value rather than how much you promote yourself. On Reddit, subtle marketing is acceptable, but the focus should always be on the content's worth.
