This, but not just for Instagram. I know people who have separate "pages" on Facebook to represent different interests. I know people who have multiple Twitter accounts for the same reason, and even more that I wish would. For all of its weaknesses, Google Plus took a step in this direction with circles. I think streams would be even better. P.S. Tags could be better still, but only if they're used consistently. My experience with other places/tools that use tags is that never ever happens, so I'd go with streams.
