What AEIOU said. BUT only if mechanics links could be formatted to be unobtrusive.

That said, with the current formatting, only linking the first instance would be fine, but why just one time per snippet? Why not one time per article? (which is how it is now if you use ignore all further instances after linking the first instance)

When I started using RW, I would link all instances because I liked the idea of being able to click on a link in context rather then trying to remember whether it was linked above and scrolling up to find the linked term in a large topic.

But I quickly came to rely more on the "Content Links" section in the right navigation column. Actually, now that I think of it, I could do away with all link formatting. As long as the linked-to topics are listed under the Content Links section, that's really all I need.
