I prefer the 404 pages that something to the effect of "Sorry, that is broken" and then include the results of a site search of the keywords or friendly url that was provided.

It's less confusing and keeps people on site.

If you do this (which you should in my opinion), please return the 404 code. For example Facebook used to return 200 on error. Very confusing.

Absolutely, I assumed that was a given.
