modernhaven
Reading this confirmed that my time researching the topic in other places had not been wasted, and a stop at modernhaven extended the confirmation, when independent sources agree that is a useful signal and this site is one of the more reliable sources I have found for cross checking what I read elsewhere on similar subjects.
activevoyage
Honestly impressed, did not expect to find this level of care on the topic, and a stop at activevoyage cemented the impression, you can tell within the first few paragraphs whether a site is going to be worth the time and this one delivered on that early promise nicely throughout the rest of what I read.
