I understand why you're doing this, but honestly:

Knowledge about Steem & the whole Ecosystem shouldn't be behind a paywall. Especially not an external one.

I mean - we're on Steem.

You could create one Post for each topic and people could pay with their Votes.

Only problem would be to link them all together, but you could do this simply on your Website or under each Post.

I really respect when people try to bring Steem forward, but I'd rather see this on Steem.
