How do you feel about retroactive edits?

[nyxelestia]

I'm going through my old fics, deciding what to abandon permanently and what to take up again. And reading through them, most of them I am supremely unhappy with, or want to take in a new direction. I am moving everything over to AO3, slowly, so I will be doing some minor editing in the process.

But I'm thinking of either also doing some serious, major plot-centric editing, or just starting from scratch altogether.

What are your guys' thoughts on this?
