Appropriate that I just got my first obvious ad in Gemini last week. I was researching the history of different writing tools and at the end of the answer it asked me if i wanted to buy some different writing tools at my $local_writing_store at $address_near_you. Was kind of taken back by integration of geolocation of my answer. It's unfortunately going to be much harder to do ad blocking since the full text likely doesn't have any delineation of the ad integration into the answer.
