He is one of the few (only?) person who when talks publicly about this or that space projects or ideas, tries to include ALL potential costs into big picture, even if they are very rough estimates. Usually when corporations or officials speak about space, they cherry pick some single issue, or maybe a few but not all of them. E.g. talk about weight but forget about cost, talk about weight and cost but forget about cooling. Or when companies talk about any complex gadgets in space and forget to account for them being space based, thus more complex and expensive. These incomplete PR statements are useless for regular people outside of the industry because we lack a lot of knowledge to fill the gaps. But reading his posts we can very quickly and reliably get basic understanding why some ideas are dead ends for nearest century despite being hyped, and why others are potentially interesting. Also he references a lot of sources in his posts, which would be hard to find but here they are linked in the relevant articles. And finally his roasting of the Space Disgrace System is worth it on it's own really :)
