What I created is not a core solution, that one is a lot more complex because it has to support inline editing too.
I just wanted to help people who need a cleaner Title SKO.
I tested this in DNN 484 and DNN 5.2.1 and I missed the issue that it does not work correclty if your not logged in in DNN 5.2.1.
Since this is kind of off topic, read my comment on codeplex about this.
I created a skinobject for DNN 5 now, it's on the codeplex page (and will not work in DNN 4).
The cache should not influence this IMO, because I now used the DNN5 way to retrieve the page title.
Anyway, this is not a reason to NOT incorporate something like this in DNN core skin objects, but that will take a lot longer..
