Do you pay for any Memex Upgrade currently? If not what is missing for you?

We don't take venture capital investments so we never get into the trap of producing free services for growth and in exchange of your data that can be monetised. Therefore it important for that we build a service that is valuable enough that people want to pay for it.
What are the features (or other things) missing that would make you pay for Memex?
