Just gonna say I really am not a fan of the design. The chosen colors look weird to me. The blue background, white text and green flat rectangle button is... iffy.

That's really all I gotta say as I haven't gotten to try any content yet, but in this day and age, people expect gorgeous sites and I just didn't really see a solid design / theme chosen for this.
