WIP: interactive tutorial drafts

This is a collection of ideas for an interactive tutorial that should be displayed after signing up on any tree.

Goals / constraints / rules

• interactive --- Don't explain; show!
• short --- three to four simple steps
• clear --- short sentences, no digressions, no philosophy
• usage-oriented, not feature-oriented --- don't introduce features; introduce usage patterns / motivations instead

Things to cover

NOTE: this is not a list of steps. Some topics (pools + springs) could be merged. A list of features followed by the motivation.

1. tree vs forest --- "How can I contact my arborista?"
2. rivers --- "How can I find content that is relevant to me?"
3. pools --- "How can I organise content I like?"
4. creating a post and using springs --- "How can I share with others?"

Interactive stuff

• create a river or select from a list of useful rivers; don't create default rivers
• ...?
