I'm done with this. If someone wants to maintain it send me a note and I'll transfer the repo. Or just fork it, or whatever.
Timeago plugin for GNU social
Thanks to the timeago jquery plugin which does all of the heavy-lifting.
- Make sure the files are in a folder called Timeago if they're not already
- Put the folder in your /plugins/ directory
- Tell /config.php to use it with: addPlugin('Timeago');
