Many silos offer the ability to download a copy of some of/all of your data. If this is of a high enough quality, it can be used as the basis of an indieweb site, or be imported into an existing indieweb site.
Indiewebcamp Creators who have imported previously siloed content into their own sites:
- Tom Morris imported all his old Twitter content and (?) some of his Tumblr content into tommorris.org
- Barnaby Walters imported all his old Diaspora content into waterpigs.co.uk/notes
- Ryan Barrett imported many of his old Facebook posts with facebook_to_wordpress.py after he started POSSEing. Details.
Articles about data export

Code to assist with data export/import
- diaspora-export — a python script for downloading all of your public Diaspora content (as the diaspora exporter doesn’t include your posts for some reason)
- freedom.io transfers your siloed posts to a blog or cloud storage provider with structure and formatting intact, including comments, pictures, tags/mentions, links, etc. It's very immature and incomplete, especially the UI, which is horrible, but the functionality largely works. It migrates from Facebook, Twitter, Google+, and Instagram to Dropbox, Tumblr, Blogger, or WordPress (self hosted and .com).
