HubPages does not form a fertile field for Gyro Gearlose or Gallileo.
- recipes and food hubs get lots of hits;
- most hubbers are American women at home with responsibility for meals, who own both a freezer and computer and who also Hub;
- freezer meals save time for hubbers;
- it's not a machine choice - persons who choose the Hub of the Day love recipes and - I guess - are women at home with responsibility for meals; (or web analysts who know most hubbers are women at home with responsibility for meals);
- recipes are a safe choice;
- esoteric topics don't work on HubPages;
- HubPages works best for mass market topics.
It's not the place to announce a scientific finding.
