I don't bite, all that often...
There is a lot of debate over this at times, and I know many keepers do feed heart as part, the base, or the sole diet for Discus and swear by it. It is worst as a sole feed, eben if you agree with feeding it, where it makes 100% of the diet with no suppliments. If you are going to feed it, you should make it as your own mix 
The link to fatty liver that I remember from the research I did after getting my discus (should have done that after
) that makes me against it. The stuff is packed with Protien, and you can work with that if you like to oversee the claims of a rebel few 
If you do choose to feed it, make your own mix. There are many recipies on the net, but look for one that has about 5-20% heart base to the rest of the ingediants. Some mix dried foods with their mixes, and that is fine so long as it isn't going to fall appart when wet
None taken
Like anything else you read on the net, you should always do your own research into things with other off-line and on-line sources. You can never get a whole answer/argument from one persons opinion/experience. The "consensus" on a single forum usualy isn't enough to go by on its own either.
A fair few examples of foods there from Mike. I'm a bit
on the first two, but agree that all that follow are good foods 
That is something I deffinately agree with

I dont know where rabbut gets his info from but I dont think its personal experience as much as it is pseudoscience. No offense.

A diet of practically everything fishy food wise......I would add to the abovebeefheart, turkeyheart, krill, mussel, shrimp, prawn, whitebait ( some will some wont) a varied mix of dried foods..whatever they will eat, mine wont eat flake.(so it goes in the heart mix), bloodworm, cichlid mix.....
