Awesome! Thanks for the info @thefln. I have a Snipcart site going live in a week (I hope), so I'll dig into the inventory management docs a bit.
Also there's a lot of good info in the comparison articles you linked to.
Lastly, a developer portal would be AMAZING! I mean seriously, how many business owners who want to sell their stuff online know enough about web development to implement Snipcart on their own? They need dev help, and Snipcart can help the devs a lot by providing a portal to manage multiple sites.
