I guess it's a question of personnal choice. In terms of strategy it's interresting since it provides a lot of expertise, allowing you to reach the cap much faster and then giving you more freedom to optimize our character. And of course the huge gift of strength it provides is a real icing on the cake.
However I tend to think that it's less awesome once you start to be really well stuffed in DS. First because it's easy nowadays to reach the expertise cap (using only reforge) so it removes half of the trinket good thing. And also because our actual stuff tends to favor a lot strength.
I tend to think like that (I take the risk to say something obvious but need to do that to explain) :
-Expertise is a stat with a cap. Once capped, no need to have more.
-Strengh has no cap. The more you have the better it is.
Heart of Rage have both. Ok! How can I negociate with that? Well first I know I can reach my expertise cap easily with my actual stuff. So no problems there. I can reach good score through optimization (went up to 2600 haste score once without that trinket) so I can pretty much have a good optimization without the help provided by the expertise bonus. Interest of the trinket interrest starts to fade. I still have however the strength bonus. Huge, tasty, yummy, yippi-ka-yay etc etc... Well there are a lot of strength trinkets also in DS. And a BIS like Eye of the Unmaking can make a real difference : it's an almost permanent addition of 780 - 990 strength. Which is even bigger that the strength bonus provided by the Heroics Creche/Bone-Link trinkets (the Raid Finder version is itself bigger). HoR strength proc only last for 20 secondes. It's huge but there will still be a gap where you strength number will loose that bonus (I call that "playing yo-yo"). Combining it with Creche of the Final Dragon makes a real pair of BIS to my advice and is much better in term of pure damage dealing.
Heroic Heart of Rage stills stays in the top 10 of the best trinkets in Cataclysm and the choice to use it or no depends I think on the way you like to optimize your DK. I used it during the Tier 11 raid and it was a real blessing. Nowadays I use a creche/eye of unmaking combo trinket and it's full happiness for me. You may use HEart of Rage if you which to focus more on optimizing your stuff and reach big scores in stats like haste or mastery (depending your playstyle).
All I said being a personnal point of view of course.
