Bests & Worsts Reviews from Amazon

UPDATE: rebooted kindle fire, went back to app store ... and searhed for pinterest, then scrolled down down down until I found the Pinterst app BY pinterest (don't be fooled by lookalikes that CHARGE!) I love that I can see my and others' boards!!! UPDATE : someone pointed out -- you can pin from the 'share' option in the browser -- BONUS! happy happy .. 5 stars! Sadly, I don't see any way to pin from the browser -- but it's still nice to be able to see & review my boards :) ================== not only does it not show in the app store (but other 'pinterest-like' (some pay) do show up .. but I tried 'buying' it from amazon.com - and it doesn't show in my cloud either. BOOOO c'mon! I want pinterest on my Fire!
