Now I have my twitter data/dump, I want to host it myself which is pretty easy because there is JSON and HTML (already thought about transforming it into XML for easier transformation in the future) but I don’t understand why Tent.io, Status.net, Facebook or heck Google don’t have an option to import your twitter data?
When Twitter made the data available to you, it was clearly yours. Aka you own the rights to all of it. So you can do what you like with it now. Including handing it over to someone else to mine and use if you so wish.
It was something we talked about again while at the dataportability group, data providers who would handle, mine and make sense of your data on your behalf.
I would consider allowing Google mine the data, if it improved my already great Google Now experience.
