Turn it into a desktop app that works with Outlook and flavour of the month ERP and you just killed Salesforce. Every sales rep, sales manager, and marketer on the planet would love this.
Great work.
Yeah, a few features around this (Desktop, etc.) would be great. Outlook is an definite win, we just have to time it right.
FYI, the 'Oulook Social Connector' provides a framework already setup for this, you'd just need to implement a provider.
