I'm not sure if it's just me, but I was clicking through the arrows to scroll through screenshots on the front page of glowapp.com and found that two captions seemed to be mixed up:

"Use Glow to share your feelings with friends on Twitter and Facebook. Update your status and mood with a single click!" was next to a picture with stars; while,

"Rating is easy. Just drag your finger across the stars. When you let go, your feeling will be sent to the cloud." is next to a picture of sharing options.

Just a heads up.
