Similar to Twitter, where RT and Favorites are around - which in is an extension as in on Pinterest. But how often people to manage to understand stark differences on "Repin" and "Like" - If I repin does that mean I never liked it - fundamentally if you had a like - It is a like and repin is also a like with a different use case to it.
Pinterest About Section defines- Like: adds the image to your profile's Likes section, doesn't get added to one of your boards. Repin:allows to categorize onto one of your boards and edit the description of the Pin.
It simply means that you have a liking to a Pin its a "LIKE", but your "Repin" also emerges through your liking; call it is "LOVABLE" - and the subtle difference between "Like" and "Repin" is understood only if you had to read-through the Manual section. Naturally, it is not intuitive and you need split-second to think- What am I going to do here? Do I need this on my board or not? and then choose between these two. There seems a disconnect - where your instinct reaction is to just simply "Like" it - whatever the consequence is. The second string is whether you need that to be categorized in your section. How if you need to add a tag to just add it in your section with a text box after chosing "Like" - where you either allow it or disallow it.
Any confusions around, that you may have felt? Is that on Twitter Do you do more of RT or Favorites? (where I prefer as a user to RT a lot against favorites and on Pinterest would always Repin rather Like a lot - Since I do RT and Repin becoz the item is a "Like" invariably - as I been doing before reading the manual of Pinterest as instinctive reaction). Can these be both coupled to do away any split-second confusion? Why should'nt I simply click "Like" and then decide upon the destination on Pinterest?
