Should I include this in my ECs?

If I have a popular Instagram blog with over 400K followers, should I include it in my app as an extracurricular? I’ve been posting on it for the past couple of years. It’s not like I’m an influencer though - it isn’t centered around my life. It means a lot to me, but it’s not traditionally educational and has nothing to do with my major. I’m just scared that the colleges might think it’s out of place if that makes sense. Thank you for all your help!

If it’s meaningful to you, include it.
