One of the ways to add interesting and relevant content is to repurpose something (article, post, photo, meme, joke, recipe, etc.) that caught your attention and/or is of interest to you and may be to others as well. You can repurpose something  (article, post, photo, meme, joke, recipe, etc.) by adding your comments, asking questions, creating a poll, suggesting something, etc. In doing that you springboard off the article, post, photo, meme, joke, recipe, etc., and repurpose it with what ever you add, which I've attempted to do with the header photo and title of this post.
