I am having hard time understanding why we need this product given that WorkFlowy already provides this service and there doesn't appear to be a great demand and required innovation in this field.
No one really knows if a given product will be successful or not.
The creator of this product wrote (http://threads2.scripting.com/2013/march/myNewCompanyAndOurF...):
"Little Outliner is a new beginning. Our easy on-ramp. We want to re-introduce idea processing, and using outliners to create presentations, but this time the difference is networking. I think you'll be amazed at what we come up with in the coming months."
Now, whether they'll be successful or not is anyone's guess, but clearly they have a plan and presumably that plan involves doing something better/different than workflowy (which is a good product that I pay for).
Let's wait and see and give them the benefit of the doubt?
