There is a little discussion in the comments of a recent MO question on the meaning of the word "affiliation" in our promotion help page. If you promote one of your own publications in a post, should you disclose that you are the author? The help page says that "you must disclose your affiliation" if you promote something, but can you be "affiliated" to a publication? Perhaps "associated" would be better.
affiliated = connected to an organization
associated = connected to something
