It's took me over 30 seconds to figure out what the site does and I'm still not 100 percent. If I were a normal user, I would have bounced by now. Improve the landing page? Pictures and some points on what it does could be helpful. Good luck!
Thanks! We are working on improving a landing page with some graphics and better explanation.
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.".
