Digg.com is my biggest waste of time in English, but also my largest source of entertainment and news.

Japanese news is so boring!

So is there anything like Digg in Japanese?

Something with news and weird pictures and links to strange videos in a user-submitted format for people with short attention spans.

I second that!
I asked for a humorous people-celeb website just a moment ago but this is not the real problem .
Not the real problem lies in the fact that japanese are so damn serious that it makes tedious the most exciting thing . They just have a knack for spoiling all the fun....

Some time ago Languageez liked me to はてなブックマーク. It's pretty good, I go there everyday.
And no, they're not so serious at all
