I recently noticed that spinoza tag was used to tag a series of questions by one user who appears to be working through Spinoza's Ethics.
All of the questions deal with a translation/grammatical difficulty that is only circumstantially related to the text. It would be similar, in my mind, to tagging a question about the passive periphrastic cicero because my question was occasioned by something I read in a Cataline oration.
What criteria are we using for the creation of author tags? Should all questions be tagged if they contain a substantial quote from a certain author? Or perhaps there is a critical mass that must be reached first?
