Make Activities Searchable
Two things happen in working with contacts. You need the social aspect (meetings, email, twitter, etc) to make anything happen, and then in campaign or followup of actual relationship, you need activities. It is so easy to load up activities to drive business and results. But not to be able to search your next steps seems like a missing success factor from Nimble.
Nimble spearheaded the social need spot on. Now make it searchable and make it real.
