If you reading through posts and come across one that inspires you to post, somehow convey that. Either in the persons comments or by providing a link to it in your own post. It can be a great way for someone interested in your post to find another post they might also have interest in. The person that inspired you will know the impact they had, and likely be motivated to create more content.
