Issue: slight article name changes break old URLs?

Normal users are more likely to remember the name of their favorite thread, rather than the number of their favorite thread. For this and other reasons involving content discovery and ranking based on context, it's beneficial to eliminate contextually irrelevant information, like the thread ID, from the URL.

VaultWiki has a mechanism to handle cases where the URL might change. If a change occurs, a copy of the article (called a Redirect) is left at the old URL, while the article's name is changed and given the appropriate new URL. We avoid the multiple URL problem for SEO by always forwarding search engines to the newest URL, and making the new URL canonical.
