Yeah, I followed Richard Hoagland for a long time because he was one of the few who was SHOWING stuff rather than just saying it and telling people to take his word for it. Whether he's right or not about the exact details (he seems to stretch the data here and there) I think he DEFINITELY brings up some valid points, especially about NASA's secrecy.
i personally think him and david wilcock have some pretty good information out.
i especially like the project camelot series they interview some pretty unique ppl with some good info
