button for "follow" on chatter

Is there a way to create a button to allow following on chatter?

The chatter following function uses a sObject called Entity Subscription.  Adding a record to that table will create a follower.  You could create a model on this object and then create  a button that runs a snippet that adds a row to the model with the subsciber ID = to the user’s ID. 

Thanks Rob… will give it a try )
