Hi,

do models use Reddit to promote their work/name? How? Where?
Does it work?

Do the people who would hire a model use reddit?

In my opinion all of the major social media outlets are useful. But each one should be used differently. Use Facebook to share news and updates. Use Twitter to share images too racy for Facebook. Use Instagram to share candid behind-the-scenes images on the fly. Use Snapchat to share time-sensitive coupons for whatever you're selling. Use Reddit to share articles about you.. etc.. etc.. etc..

Sometimes it's not about the direct benefit.
