Thank you for sharing this great thought!!
Its definitely a requirement for products like Steempress to be successful. People want to get to more audience and that is to their blog on wordpress, but not on steemit. I don't have skills to comment on technical things but this 'information of the source' should be stored and preserved.
I got interested in Steempress because it adds the benefits of being on a blockchain(immutability, decentralization) with out actually creating everything from scratch. I wouldn't feel good if its hurts rather than to help.
