Something changed recently, and I didn’t like it at first 
… but this makes finding related info and “going down the rabbit hole” so much simpler.
The search (esp. advanced search) on this site is good - but you have to know the right terms. Now, if I hit a topic that seems close to what I want/need, but isn’t quite there, I’m given 5 more topics that are related - and they really are related.
Before, the suggested topics were all in the same category, which has huge breadth for interesting randomness - but now we have the opportunity to research more deeply, more easily.
