I have over 400 interviews on my site and my audience keeps asking me for a way to sort through them.
I don’t have time to tag all 400 interviews. Do you think there’s a way for my audience to tag interviews themselves?
Matt Mullenweg uses a similar feature on on his blog, Ma.tt, that lets users tag photos.
He released the code as a plugin, Matts Community Tags. You will have to create a custom taxonomy for the tags and add some additional code to your templates to make it work. See the discussion on the WordPress.org forums for more information.
