On a few GraphicRiver items, particularly http://graphicriver.net/item/image-flow-photoshop-action/84847 , the sample or details image uses a particular sans-serif font I've seen so many times, but for the life of me can't figure out what it is. I originally thought it was a FontFont font, but I scrolled earlier today through their entire online catalog w/a text sample "work like" and found no match.
Lowercase 'f' and 't' have only half a cross-bar, and the lowercase 'k' is "curly." Neither WhatTheFont nor Identifont were any help.
This font is like that song stuck in your head that you don't know the right words to, you know?
