Comming from raw SQL and then activerecord (ruby) this was my first impressions/thoughts on RethinkDB. It's just a quick braindump so take it for what it is :).

• why not have RethinkDB::RQL#inspect call run() so I can play around easier in irb. Constructing queries and see the results directly. How useful is it really to have the query I just constructed printed again?

• I was running 1.4.5 and "apt-get update" got me 1.5 and suddenly my database wasn't working. The package was released before the blogpost with migration-instructions. Edgecase, but I managed to get bitten by it :P. The log-entry could contain the url with migrations-instructions?

• Why not just order() instead of order_by(), you don't have filter_by() or replace_with(). Maybe I'm colored by active record in this case.. but less is usually more. Hard to confuse a simpler order() with anything else.

• r.connect should take a hash/json argument. Then I could do r.connect(db: "heroes"), host would default to localhost and port to 28015 as n
