Can you try a thicker font on the word mark, more like facebook? We like the lighter font too but we would like to see a more substantial look to the word mark.
#22 interesting with the white as the icon background. Not sure we like the stacked logo approach and the font is nice but doesn't seem to fit what we are looking for, maybe a bit too sophisticated.
We will keep thinking about how you could make your design better. Thanks for your hard work.
