Sorry, I'm a newbie here, I didn't know of this page and 3RR until now. My opinion,
Hyperdimensional physics is described in chapter two in his popular Dark Mission book, also given a good introduction in his Hyperdimensional Election of Barack Obama documentary. HDP is the 'scientific foundation' of his theories and will probably be central in all his future talks and material. If not "known for HDP" now, he will be eventually.
Agreed.
Since Hoagland never claimed formal scientific training (afaik), who would expect him to publish peer-reviewed articles? I agree that the 'contribution' is moved from

 How about refering to him as an "independent investigator and science speaker"?

El, why do you advocate complete deletion? IMHO, the article just needs bias-adjustments, more accurat ereformulation and citation updates.
