I don’t have Instagram but I imagine it’s a bit like the App Store. I’m waiting somewhere. I’m bored. I know, I’ll check for a shiny thing. Oh, no shiny thing. That was disappointing.
To compare, do you go to the internet regularly and check for new things? I don’t think this is the App Store’s fault. It’s not on Apple to constantly put new shiny useful software in the App Store — it’s on developers. And I’m not blaming developers. Making new shiny software is hard. There’s already a whole bunch of software. If you have a problem, chances are it’s already been addressed.
Constantly shiny + new ~== a good App Store.
(~== Not necessarily equal to. Did I just invent that?)
