A reminder that +1s *for web sites* are going away. You *can* export them to other places. I chose to move mine to Pinboard. One nice thing Pinboard does is archive the pages you bookmark, so now the content I +1'd is more stable long term.
In the process I found and fixed a bug where the timestamps on the plusones takeout export were wrong. It was broken for about 5 years and no one noticed :(
If you want a proper export file you can use for now. Prod push should be sometime this week...
