App site with reliable ratings + comments? While Android Enthusiasts is nice, it's still a very small site.

I need to find some applications for Android smartphones, and was wondering where people went for ratings + reliable comments from users? PlayStore? Other?

Incidently, I need to find two applications for a friend who wants to study English and Chinese, but don't know where to go to find the best apps for this.

Thank you.
We'll reliable is somewhat subjective. But I can recommend App Brain (Play Store App) and App Aware (Play Store App).

App Brain provides some additional features compared to the Play Store and App Aware allows you to follow app streams based on a topic (games, sw development, etc.). Both try to suggest you apps based on the apps that you have installed. And both are not a new app market, they just redirect you to the Play Store if you want to install a app.
