I would say that results provided by this extension aren’t always going to be what you expect, but even these mismatches can be entertaining in their own regard.
For example, for now-deleted post from r/todayilearned (by the way, I highly recommend it as a source of daily random interesting facts) about “Conan the Bacterium” Entity Explosion returns:
TIL about "Conan the Bacterium", an organism that's been around for about a billion years more than us, can survive almost anything and will likely outlast us all.

And for the Wikipedia page about “Conan the Bacterium” (which has a funny name in Latin as well, meaning “radiation-surviving terrible berry”), the extension predictably returns correct results, since Wikipedia-based projects are deeply interconnected.
Overall, I think it’s a nice extension. It the best case you quickly get a selection of links about a thing that already captured your attention, in the worst you get a chance to learn about something new. You can also improve the addon queries.
