Surpricingly nearly 25% of all sites that submitted in my general directory are one of these. Most of these sites are spam to me. The majority of them looks the same. And the idea is dull IMHO. However, Why are so many people chosing these trivial subjects and not some porn term like: hairy legs(which isn't sexy, but very effective when generating easy income). What is the drive that makes so many people create a site about Insourances? Is it because it's interesting to write content about
I've wondered the same myself. I think most people see $$$ and don't really think about the full equation of what it's going to take to get that money. You can't overrate how important looking at the competition is, when thinking about entering a market.
All variables should be taken to consideration. If you enter a too competetive market, you might end up in spending too much resources instead of gaining money.
