I wouldn't. Three per day seems too much and would probably fall into the trap of being shallow knock-offs of stuff that is already being done.

What would appeal more to me is 3 per week with each idea built out with things like:

Size of potential market,

Target industries identified,

Competition and Internal Substitutes,

Educated guess as to why this doesn't already exist,

Target buyer roles within companies for B2B or target buyer for a consumer product or service,

Maybe a couple more points like this

This could get very involved - but I am thinking like a nice succinct one page version covering these points.

This is getting closer to something I would pay for.
