I do not think "they make your product look well thought out." is why. I think the need is to read a clean, clear symbol instantly. Apple, Golden Arch, Handica

I do not think "they make your product look well thought out." is why. I think the need is to read a clean, clear symbol instantly. Apple, Golden Arch, Handicap-Sign. Because of this, a lot of design majors learn this branding style. Readability is super important in mono-culture, so is clean interface. Furthermore, vectors are used due to their ability to scale to any-size, and the standard tool, Illustrator, just more naturally makes this look than say a St Gaudans Buffalo Nickel design. It's a typical copycat style that happens in design and art. Around 2005, I noticed flying bird silhouettes everywhere.
