Hitting the ‘Reblog’ button (assuming that it’s enabled on the site) allows republication of a blog article on your blog. By default, a reblog is categorized in the really useful (not) category ‘uncategorized’, so for best results it’s a good idea to edit the reblogged post and amend the categories (and perhaps the tags, too) appropriately.
WordPress support has an article that explains how to reblog.
There’s some debate over whether it’s good etiquette to reblog posts (discussed at length by Elizabeth on The Daily Post). Personally, I think reblogging is a good idea; I view it as a compliment to the originator and it helps to expand the reach of interesting posts.
How to enable the reblog button on your site
Go to Settings > Sharing and select ‘Show the Reblog button on posts’. Simple. (If you want to disable the button for some reason, select ‘Don’t show the Reblog button on posts’. Equally simple.)
- The Reblog button only shows to users who are logged in at WordPress.com
- The Reblog button only shows if ‘likes’ are enabled on a post
- The Reblog button won’t show on sites that are private
