Back in the days people were one click away from top rated, most recent, and top rated international articles. Current interface just isn't user friendly, and unless I'm really bored, I won't bother going through it all just to find some interesting articles in English. I think that might be how other people feel as well, and that might be the reason they don't read or vote articles.
Besides, section top rated articles shows old ones. It is really tough to find new newspaper worth subscribing, not to mention all the journalist missisons spam.
