Its about the interesting-ness of the post. Conceptually this could be made more interesting. Say I actually put together my own step by step set of videos/gifs of how to assemble the battery... Maybe that would help bring some originality. Perhaps I then went on to see what sort of crazy things I could power with potato batteries linked in series, that might also help. Still other creativity is needed. This basic post is what it is, a boring rehash of very very basic information which is readily available elsewhere on the internet, it brings nothing to the table, no originality, no new content, nothing we cant see done better elsewhere.
