A doge is an elected chief of state lordship, the ruler of the Republic in many of the Italian city states during the medieval and renaissance periods, in the Italian "crowned republics".
The word is from a Venetian word that descends from the Latin dux (as do the English duke and the standard Italian duce and duca), meaning "leader", especially in a military context. The wife of a doge is styled a dogaressa. 
From Facebook video embedding to 3D videos and advanced commenting, Facebook unveiled its plans to continue moving beyond social media to become a complete content system, much like Google.
Over the last couple of years, Facebook has unveiled numerous new tools and integrations within their site that takes it beyond its original social network capabilities. It’s now attempting to rival YouTube as a video publishing platform and wants to facilitate all of your communications through its Messenger App, which has replaced texting and even email for its current users.
As a business owner, what does this mean to you?
If you aren’t already producing videos, start doing so now. Not only is it a powerful SEO (Search Engine Optimization) tool (providing strong back links from YouTube), it’s now the strongest content to help you reach your audience on Facebook. If you have questions about how to do this, contact your Total Social Solutions account manager or contact one of our marketing experts for a personalized consultation.
Facebook Messenger, up to this point, allows you to replace text messaging. However, the Facebook Messenger is now being opened up to developers, called Messenger Platform, to build more apps to increase the richness of the Messenger experience. More importantly, however, is Messenger Business.
Facebook’s David Marcus presented how the future of Messenger Business can look, allowing businesses to communicate with their customers even more through Facebook apps, specifically through Facebook Messenger, to bring back the personal experience and convenience via e-commerce, especially on mobile devices. The marketing potential here is huge, as it’s possible we will soon be able to send marketing messages to customers via Messenger to personalize the Facebook engagement experience and effectively increase ROI via Facebook. Basically, we predict you will soon be able to send Facebook messages to users who have opted in to receiving communication from you, much like you would send out your email newsletter.
