If you are in it for the rep, you will burn out pretty quickly. The fact is, while the shiny badges and reputation make answering questions exciting, most people are here because they
- enjoy the sense of community
- like being able to disseminate their expertise
- benefit from the expertise of others
If you've posted a good answer, you get the satisfaction of knowing you've posted a good answer and will probably get some rep for it. No one is obligated to upvote your answers.
What you can do is:
- Throw in a few answers on mainstream, straightforward questions. If you focus exclusively on obscure, niche topics that not many people will see, you are unlikely to get votes
- Format your answers nicely
- Don't whine.
I disagree with your feature request because it would completely devalue reputation. Churning out a hundred throwaway answers a day is easy; writing four or five that people actually find helpful is what its about.
