I'm an ECR and only have six publications. If I receive a Google Scholar alert I will aways check to see what the citing works says about mine. However, I'm not sure if that's the 'done thing.' More senior colleagues seem to think it is rather unsophisticated to do so (or, at least, think that admitting to it is rather unsophisticated...) So I was curious, is it one of those things that everyone does and no one admits to, or do you simply stop caring past a certain point?
