Blog export/import w/links conversion

As I’ve been tinkering on Write.as in advance of launching an instance, it occurs to me that it might be useful to have a way to not just export entries but then import them into a new account, whether on the same instance or another.

One useful feature could be the ability to input your new URL during the export, or your old URL during the import and automatically find/replace anywhere you had internally linked to your own posts, so all the links continue to work in the new instance.

(I was mostly imagining folks who start out on Write.as but then find a new instance they’d prefer to be on, and finding an easy way for them as a user to migrate.)
