I'd start with the basic customer service model.
What do the customers actually want from such a product?
It's becoming easy to list what they DON'T want, which is much of what they are getting.
Here's a list off the top of my head on what a new service would need to provide:
- Impartiality.
- Intelligence on the market conditions.
- Integrity.
- Fair,consistent grading no matter who the submitter is.
- Solid, secure,attractive holders. Reasonable font size.
- Population reports with full data on variations etc
- Registry sets, easy way to register them with ownership changes.
- Reasonable wait times.
- Responsive, interactive service with submitters
- Some Hobby altruism to ensure the life cycle of their product and the hobby itself
- More integrity.
