That's certainly a good point, but it seems wasteful to copy, just in case. Surely though multiple links would decrease that chance.

What I was really getting at was wholesale monotonous rewrites. A lot of the web in my mind could be DRYed up. But perhaps redundancy isn't the issue I think it is.

I do feel I do a lot of toing and froing with searches. More than in the past, but possibly that's just because there is so much more information to filter. I'd have thought that healthy linking would help search engines.
