Instagram's filters are also a weird, annoying, inauthentic, dare I say pretentious concept. It's like it wants to infuse vintage nostalgia into the present.

I like Postagram's concept on its own premise - and I think it'll work great for them.

It's about discovering a market and a userbase, and these people have done that. I can't do anything but with them the best.

It already uses Instagram, so it's not like it's to blame for the aforementioned downsides. They are latching onto the mentality and turning a profit from it. You don't even have to like Instagram to do that.

I don't like Instagram, but I wish I'd come up with this idea. I don't have to like Justin Bieber's music to sell ear plugs near his concert.
