I think one of the biggest challenges is scale/breadth. For some things like Movies, we have lots of critics and there is demand for it. I work in web hosting reviews. Everyone technical has an opinion and non-technical too. The average HN reader and a non technical person starting their first blog are very different use cases and demands. I see way too often the 'why don't you just get a VPS and do it yourself it's cheaper' advice to basically anyone. Those are the kinds of people quite actively trying to 'help' newbies. And the reviews, well, it's not a product most people try a lot of different companies nor have any sense of how theirs might stack up. I've got to be one of the most experienced people in terms of number of companies used (I probably had accounts at ~50 companies this year), and I still wouldn't be comfortable writing reviews. It's too subjective and biased.
