Blue post is the common term used for a post made by a Blizzard employee on Blizzard's official World of Warcraft forums.
Unlike other forum users, all their text appears in blue; hence "blue post".
Official resources[]
A tracker feature is provided by Blizzard themselves to track all the current blue posts. However, the blue posts they have archived dates back to 10 June 2016. Any blue posts prior to that date are no longer available on the official site so an external website would be a better alternative. Any blue posts here can also disappear at anytime.
External resources[]
Many third party websites track and archive blue posts:
- Blue Tracker.gg (maintained by Magic Find, owners of MMO-Champion)
- Wowhead (see Wowhead)
- WoW BlueTacker - Only contains posts from 2009 and earlier
Appearance on Wowpedia[]
Within Wowpedia, links to blue posts may be identified with the 
icon and quotations will appear like the sample below:
