I would like to point out that a number of these 100% delegates are not so technically inclined, but were voted up for their other contributions that would be funded by their delegate position.
Of all the information regarding delegate setup etc there really isn't much regarding feeds, and it is considered an optional element because of this I think.
I think rather than singling out the 100% delegates though, if you just make the feeds part of the standard for all delegates for their setup and provide clear documentation on that portion of the process, then it should fix itself.
