No because twitter isn't just for pictures etc.
Instagram is just another platform like Myspace in the way that people only use it to share stuff about their life.
It'll die in the next few years just like Myspace did when something new came along.
Some people actually use Facebook and Twitter to catch up on news about several things, wether it's an artist, actual world news, movies or well, anything really.
Of course people also share personal stuff on there but it's different in the end because Instagram and Snapchat are nothing more than picture sharing platforms.
They literally offer nothing more + let's be honest, who actually uses Snapchat except for like 15 y.o.'s?

I never saw the point of that platform.
