What's a good Android app for making a little extra scratch just by sharing my opinions? I'm talking quick surveys, not some huge time commitment.

Alright, so Surveys On The Go is what I've been using when I'm, like, waiting for a build to finish or something. From a technical standpoint, the UI is clean, which is a huge plus. No janky interfaces here. The survey matching is pretty good too; I'm not getting bombarded with stuff that's totally irrelevant. Payouts are via PayPal, which is clutch – no messing around with weird gift cards. I've noticed it only sips about 30MB of RAM, which is nice 'cause I'm usually running a ton of stuff in the background. The dev team really thought about keeping it lightweight. It's not gonna replace my day job, but for a few minutes of answering questions, it's a decent way to pad the wallet a bit. No spaghetti code situations here, seems like they kept it pretty tight under the hood.
