Two more announcements for OpenID adoption — but this time on the consuming side (as opposed to my originally incorrect report about WordPress.com — for now, they’re only serving as an identity provider).
The first is Shopify, a great Rails-based custom store application. As Alex points out, these guys really get it right — and make it super easy to create compelling marketplaces. And now, it’s super easy to log in with OpenID.
Meanwhile, IconBuffet has gone through a major overhaul, becoming something of a social network for … icon enthusiasts! (Sweet!) One of the more existing aspects of the relaunch (at least for me) is their use of OpenID: you can either create a new account with an existing OpenID (say, your WordPress.com blog URL) or you associate your existing account with an OpenID. Either way, they too’ve made it really easy to get going with OpenID.
I imagine that these won’t be the last of the increasing deployments of OpenID in the medium- to long-tail (read: not Google or IBM, but small business community). What’s so existing about these recent additions is their proximity to commerce — and how folks like Shopify could eventually weave a web service that allows you to check out — entirely by way of logging in to your OpenID provider. If you choose a good OpenID provider, you can start to see how the CardSpace metaphor makes sense — just like when you go out to eat and depending on whether it’s a business meal or a personal expense, you’ll use a different credit card to pay.
The same thing is true for OpenID — where you can have as many OpenIDs as you like and you can pick among them for different uses or purposes. It’s only a matter of time before I go to check out at IconBuffet, I login with my WordPress.com OpenID and I’m able to use credits that I’ve purchased on WordPress.com to pay for my icons — with no need to reach for the credit card, to fill in my address info or any of that ever again!
Now, if that doesn’t sound exciting, you might want to check your pulse. 😉

If only every site was like IconBuffet… I mean in its use of OpenID. If you have an id from elsewhere, you can use it here, if you want an id, you already have one because you signed up with us. I don’t mean that I wish every site was a social network for icon-lovin’ folk.
