Hi Baron, thanks for your input. I never even thought to talk to you about this. If you don't mind I'd like to discuss further some marketing strategies and website development. I'll PM you.
Congratulations on building something. It's gotta feel really rewarding. I do not think I would pay for this. Leave alone 10$ / month. What value does it give me that other free sites already don't? I can't even see the site now. Shinyapps.io looks suspect. I think you can do better!
