Why is the post ID duplicated in permalinks on SO (or any other Stack Exchange site)?

For instance:

http:// stackoverflow.com/questions/1732348/regex-match-open-tags-except-xhtml-self-contained-tags/1732454#1732454

Why have the extra digits when this would be enough?

http:// stackoverflow.com/questions/1732348/regex-match-open-tags-except-xhtml-self-contained-tags#1732454

Because it's not enough. See

RegEx match open tags except XHTML self-contained tags

versus

RegEx match open tags except XHTML self-contained tags

  • This depends a bit on the sort order. Be sure to sort on votes, or log out of SO, before clicking the above.

  • As of now, those links doesn't seem to make any difference anymore.
