With AutoContacts you can get lots of info on your contacts.
Start by using the Tasker action "Plugin->AutoContacts" and writing a name in the "Name or Nickname" field. Then you can use any of the AutoContacts variables to call, email, sms, or anything else you want to do with the info. You could navigate to a contact's home address, or open his website on a browser. You could even create a notification when his birthday is near. It's up to you what you do with your contact's info!
These are some of the variables you get when you query your contacts:
%acname - Contact Name
%acnickname - Contact Nickname
%acnumber - Contact Phone Number
%acnumbertype - Contact Phone Number Type (Work, Home, etc)
%acemail - Contact Email Address
%acemailtype - Contact Email Address Type (Home Work, etc)
%acaddress - Contact Physical Address
%acevent - Contact Birthday, Anniversary or other
%aceventtype - Type of the event in %acevent

%acdayssinceevent - Total Number of days since the event first happened
%acmonthssinceevent - Total Number of months since the event first happened
