I wonder if the effectiveness of #1s is based on the person's interests and what itches they are scratching. Since for many devs their first inclination is to scratch their development itches... however in a fair few cases you are putting yourself in a market where your own audience might be able to do as well/outdo you, making things tougher. When you're writing tools for less technical groups, and taking the effort to make them highly usable by those who are less technically savvy the odds of running into similar problems are lower.
