There are a lot of terrible things out there but one that really bugs me is all the misinformation/propaganda that the internet causes. I didn't see it coming, I thought the web would make people more informed, not less.
On the front page you state what could be interpreted as an anti-capitalist, left-wing bias: information that governs the world should be controlled by everyday people, not governments or corporations. And yet 'everyday people' can be just as biased, bigoted and self-interested as governments and corporations. Curation does not in and of itself imply impartiality or truth - if anything, it can magnify the biases of a group through network effects and positive feedback loops.
When i Click on a story (and to a lesser extend, when i look at the front page) my eyes are zigzagging around trying to latch onto something, but everything seemingly craves my attention equally.
Large headlines, up vote trackers and huge (semi-informative) pictures all over the place is really a bit too much.
Make a list, have the photo the left of the headline, and maybe a blurb on the right or when hover-over.
