Thanks for reading the post. What do you think is wrong with the del.icio.us formula?

It would be nice to have a less misleading title. I clicked to find out what Digg's algorithm is.

The actual algorithm is more complicated than that, is all.

Wait - the title doesn't include Digg, so how exactly is it misleading? Maybe you're being sarcastic and my sarcasm detector just isn't well-tuned.

I thought karma had an influence on how something appears. If not what is the point of karma?

Yippee! Thats great. But how did u findout delicious's and stumbleupon's? By reverse engineering technique... like... Were these found out(or guess-worked) by constantly keeping track of the ranking of content?

Joshu, i think the del.icio.us formula is right, or they might just be using a different time constraint than 1 hour(maybe 2hrs or anything else). Because to findout what's popular they dont require any complex stuff. Simple math as specified in Danny's post is enough for their task.

Go Danny! Go!!!

I would trust user 'joshu' on matters related to del.icio.us.
