1) taking sporadic notes, but not full urls
2) attempting to follow your same trail again
I often find I can't even, with knowledge of what I read/saw find the same sources again, using the same tools and sites without basically taking detailed notes. The idea that information is public and can be connected in the same way is preposterous, but only via experience.
If you have an insight, or a linkage between facts and events, please document it in a way that is shareable and findable. I too saw the ad for the virologist post-doc position in the Wuhan lab. I think lab escape of either a wild virus or a slightly modified one is likely. It doesn't mean that it is nefarious.
I think a full text and graphical log of the research process would be highly productive.
There's so much distraction, hysteria and extremely questionable science reporting. Without having in depth knowledge about Mainland China, I'm not sure if I'd not fallen for some of the misinformation as well. So yes, it's extremely important people document what they see and understand, and share it with other in a way that makes it easily accessible. When many journalists do a bad job at fact checking and questioning their sources, we have to be better than that, else we just contribute to the noise.
