Whenever people ask which IG they should Pin on their account I always do the ones that have gotten you the most feedback. Using mine as an example every-time I exchange instagrams people always ask me if the tigers are real, or about partying in Ibiza. I leave it pinned because I want people to see those when I follow myself because it will create engaging conversation and will get a person 1. interested 2. talking to me where I can ask simple follow up questions to get them talking about themselves, where they have traveled, one place they are dying to go etc.
