Very accurate, but most of all, Instagram is where the girls are.
The filters Instagram supplied to the common end-user brought girls in by the truckload. All of the people that recommended Instagram to me, begore it was well known, before they were acquired by Facebook, all of the people that pushed Instagram by word of mouth were girls, and almost without fail, photogenic girls, or there somewhat less-so friends.
This class of girls also went to Snapchat, but for obviously different reasons, in particular, as a pseudo-forward security toy (sexting via app). Something they presumed to be, mostly “secure enough” for the moment.
This split, of forward security contrasted against accessible cookie-cutter photoshop filters that place many images on a sentimental pedistal or permit the ability glamourize one-handed, were what precipitated the viral runaway growth hack the differentiated each from other varieties of photo sharing, like flickr.
