Today Salesforce.com finally unveiled Do.com, the new service we covered previously. VentureBeat has coverage and a sign-up code.

I expected Do.com to be a rebranding of Manymoon, the project management and collaboration application the CRM company acquired earlier this year. Instead, it’s a new application based on Manymoon. It’s not clear whether Salesforce.com will keep Manymoon alive, or drop it in favor of Do.com.

Do.com is a task management service for small businesses and groups. Unlike most of Salesforce.com’s services, this one is not for the enterprise. It’s built on Heroku with Ruby on Rails (Manymoon was also built with Rails) and HTML5. There’s a native iPhone app, but thanks to the HTML5 interface the Web app should work on most platforms.

Do.com will compete with other task management tools like Asana, which just launched last week, Teamly, Teambox, Cohuman and others.

Services Angle

Do.com seems mostly like a toy to show off the capabilities of Heroku and HTML5 rather than a serious offering on Salesforce.com’s part. But it’s an expensive proof of concept- Salesforce.com reportedly spent $2.6 million on the domain name alone. It does demonstrate next generation development stack based on HTML5 and a platform-as-a-service, but by producing a simple Web app it falls short of being really compelling. What it fails to demonstrate, at least as of yet, is how Heroku apps could integrate with the Salesforce.com/Force.com architecture.
