Likes vs. Favorites
It seems like everything is social today, and everyone has their own way of marking highlights. Facebook has the Like button, Twitter lets you Favorite tweets, Google has +1, etc. While all these are basically the same idea, I find that naming plays a big part in how I use them
On Twitter and Flickr, where the term is Favorite, I use them to make a curated list of things I might want to find later. My true favorites.
Contrast that to Facebook and Instagram, where the term is Like. Because it feels less committal, I find myself liking all sorts of things. Funny post? Cute picture of your kids? I’ll Like that. It is more like a pat on the back instead of giving them an award, quicker and less permanent.
When developing an app, for you or a client, think about the terms you use and how you want people to use the feature. I’m sure other people don’t over-think the Favorite button like I do, but some will. Use language to lead people where you want them to go.
