I think it's a big opportunity that the Fediverse has largely slept on. A lot of people shrug it off, but Facebook, Instagram, Medium, and a number of other places offer an export archive of your data.

Some of it isn't all that usable, but there's something extremely appealing about being able to take old parts of your social graph with you, and merge it into a new identity. A fixation I've had for the past few years is consolidating all of my data into one place, under one identity, and I'm exploring the possibility of writing data converters.

Interestingly, Pixelfed allows you to import your Instagram archive, and it's fantastic.
