On a non-retina screen, the font weight of 100 looks not so great. I'd recommend to use a media query to check the DPI.
When I saw "Discover" I expected some examples. Your product is intriguing, but I don't think there are that many people that will go "Oh, now I can finally make <insert object>". HAving some examples would be a great way to show what can be done and inspire your customers.
In fact, there is a media query checking for this and changing the font weight to 300. Actually it makes it 100 for retina screens. It's tested and works in several devices - let's check if there is any error in loading the 300 font weight from google fonts though - thanks for the tip.
Your comment on examples is very correct and we've been advised at least 3 more times here; we are definitely doing this soon! Thank you again for your comments.
