I don’t really have anything helpful, but for what it’s worth, I never took to Instagram. I’m sure I could find plenty there of interest if I had the time to spend on it, but my Twitter feed gives me the kind of quick-hit laughs and entertainment that will keep me going back there instead.
It kind of depends on the context of your question; if it’s “what can I get from it?” see above; if it’s “what can I use it for?” uhh, I dunno.
