I like one or two other Stack Exchange websites but they have really low user participation. I want to promote those websites by mentioning their names with a link in my User's Profile about me section. I have seen some users doing this on our site on their profiles.
Is it ethical to do such thing? Doesn't it conflict Academia's website policies?
related question, but not a duplicate: Why no link in the header of the main site to our 'About' page?
