In selecting UI fonts, it seems that fonts with the most readability, and the least "character" are always picked.
Such a font allows the main content relating to the goals of the interface, be it pictures, conversations, or conversations, to stand out. These fonts, usually used in buttons or admin info (dates, user time posted), serve their core purpose before quickly fading away from the user's attention.
When we want to check for a photo album, for example, our eyes quickly search for the name of an album and once we find it, we move on to the album content, not remembering the font that easily enabled the quick search of an album name.
What really is the consideration, if not, when picking such a font for a website or application?
