This is kind of why people are meant to have blogs. A network of blogs where people can maintain historical records of their thinking, for example. Scott Alexander is a great example of this: every so often we get a "contra PERSON on SUBJECT", a long well-thought-out discussion with nuance and a good-faith attempt to understand the argument under criticism. And people reply with their own long-form blogs in a similar vein.
