instagram vs flickr?

[john]

so i have account in both sites and i can say i still love both. what i love for instagram is its community, what i love for flickr is image size. so the thing is that i used to be a bit famous on flickr and i stopped using it because of instagram. whats more in order to get famous in instagram you have to have an iphone and not everyone can afford that. so what should i do stay on instagram or move to flickr. btw ill by my first dslr in a couple of months.
