how do I delete a chatter topic? There is a typo

I was thinking that I could create a 'data feed' for Power Pivot using REST API... has anyone done this? Is this possible?

there must be a way to use salesforce as a data feed for power pivot? REST API?

I'd like to connect PowerPivot to salesforce. It seems that this should be possible using the "Connect to a Data Feed from Other Feeds" functionality.

Could someone help me how to do the setup in order to connect to salesforce?
