Marissa Mayer has a new photo-sharing app. It looks like it's from 2009, but boomers might love it.

• Marissa Mayer just launched an app called Shine, which is meant for group photo sharing. 
• The design and concept looks straight out of 2009, and people are roasting it online.
• But don't count it out so fast. There are uses for this among older or less tech-savvy people.

Marissa Mayer, former Yahoo CEO, just announced a new app from her latest venture. It's called Shine, and it's a photo-sharing app where multiple people can upload photos to a shared album.

My first reaction, along with the internet's was: What in the gosh-danged 2009 is this?
