Should I mention the number of followers of my blog in my SOP for grad school? I maintain a technical blog (posts are in direct correspondence with my interested field of study) which has around 150000 followers. I have two questions:

(a) Do I mention the number of followers in my SOP/CV?

(b) Would mentioning the fact that I maintain this technical blog have any impact in admissions? (or do I even mention the blog in my CV/SOP?)

Thanks !
(a) There is not harm in mentioning it. Of course, how they interpret it is up to the department. In my cohort (social sciences), there was one student with a blog that he runs that generates quite some views. I am sure he included that (views) in his application.

(b) I would imagine it can only have a positive effect on your application.
