We'll see. I do agree we're entering on a phase where people want to curate the over-information they're exposed to. I don't know if this will be the way to go, though. It's just a matter of time.
Just need to keep making enough sales to continue creating articles so your userbase increases in size. Probably a good idea to promote a newsletter to signup to for updates (possibly offer a weekly and monthly version).
Do you think it's possible to sustain this model w/out advertising? I'd love if they can pull that off.
