Hello,
It's a weird combination of two very used words.
On one hand "shout" is great for social media or communications, but on the other hand, "beta" doesn't seem like a great fit. Honestly, it sounds more like a version release of something named "Shout".
To its credit, it's a short two word domain, any additional value lies on the volume of traffic you might have.
Did you build the site? Can you give any stats on visits and referrals? Are you also behind the application with the same name on google play?
