To discourage link-spamming, one way could be:

- Have a notion of stable revisions, either marked by hand, or in the future I hope via a collaboration of hand marking and trust (algorithmic marking).

- Sell to search engines a stable revision feed.  I believe that search engines would much rather index stable revisions of articles, and they would be willing to pay for it, giving the visibility of the Wikipedia as a search target.

The advantages of this scheme are:

- Link spamming becomes useless
- We raise money
- We can continue to present visitors the latest version whenever we feel this is appropriate for the Wikipedia evolution, without regards to spammer behavior.
