Though TopProducer seems to be the most popular CRM tool in the real estate industry, I know some real estate professionals use Salesforce.com as their customer relationship management application. As of today, those of you using Salesforce have some new tools at your disposal — Google Apps!

Salesforce for Google Apps integrates Gmail, Google Talk, Google Docs, and Google Calendar directly into your Salesforce interface — this seems certain to result in some productivity improvements for Salesforce customers.
