Combining two of the most addictive things about the online universe--Twitter and World of Warcraft--seems like a good way to bring productivity in the Western world to a screeching halt.

If that happens, you can blame PlayXpert, a maker of various in-game widgets for PC gamers. The company today announced the PlayXpert Twitter Widget, adding Twitter functionality to the existing PlayXpert software, which works with WoW and other online PC games.

In-game widget engines such as PlayXpert (which bills itself as an "in-game operating system") run alongside PC games, offering voice chat, Web browsing, and other tools for players, wow gold without the need to quit or ATL+TAB out of the game to launch another app (popular examples include Xfire and Steam).

Besides allowing normal Twitter messages ("Proc on healing spells to get a buff for 15sec that adds a 15% shield to all healing spells!"), the Twitter widget can also automatically post when you enter or leave a game.
