I am using the Twitter extension node to gather Tweets, but I have to exectue this manually.

I have been told I need to create a 'Variable Condition Loop End" node at the end and "a condition that never verifies". How do I do this?

Isn't it just one that doesn't resolve to true?

For example I could say end when flow variable knime.workspace = "NOT_A_WORKSPACE". Thsi will never be true so the loop will keep running. 

How will you collect the output? Append it to a CSV file as you iterate?
