You can do the same with Google Calendar. Enter an appointment in Nimble, invite some guests from your contacts list; and it's there in Google when you look for it.
However, I did say Nimble was still beta. As I write this, the site isn't ready for prime time just yet. For example, I had problems importing all of my contacts into Nimble. Linked In and Twitter, no sweat. Facebook and Gmail ... sweat. Also: Creating new appointments and exporting them to Google Calendar worked great. Importing existing appointments from Google to Nimble, not so much.
Ferrara says some of this has to do with limits placed on the services' application programming interfaces; their APIs are deliberately throttled to prevent being overrun by requests. Some of it has to do with the fact that Nimble is still a work in progress.
Ultimately Nimble will be aimed at workgroups, so you can use it to not only manage contacts but also assign tasks and manage them as well. At that point it will likely be a paid service, similar to Salesforce.com. But individuals will always be able to use it for free, says Ferrara.
And then, maybe, I'll finally get to all those messages that have been piling up on me. Possibly before the end of the next decade.
