The "Wedding Planning" button made me think that's what it did. I thought "cool idea, they should show that in more places". Then when I clicked the Categories tab I found out that that's just an example. Or I could be wrong about that too, but that just highlights the point further.

I'd suggest putting a tagline beneath your logo that describes what you do. Don't make it too marketesy, make it explanatory. "Helpful instructions to common tasks" or whatever is better than something like "Plan. Do. Share.".

same here. I spent 30 seconds and have no idea what it does or why I want it.
