Every once in a while I (try to) submit an article to Digg.  Every time, I:

1. click the Submit a New Story link
2. paste the URL
3. hit the Continue button
4. paste in a title
5. paste in a description
6. choose a topic
7. prove I’m human
8. click the Submit Story button

And then I get the dupe message.  Eight steps.  EIGHT STEPS!  This could easily — and obviously — be reduced to three steps.  Do the damn duplicate check after step 3.  It makes about a million times more sense!
