Today Adrants announced the official launch of AdGabber, a professional networking site for members of the marketing and advertising sectors.

The platform has grown from its low-key May inception to approximately 1600 members via word of mouth and cross-linking from Adrants, a marketing and advertising critique site, to help build momentum.

The site, which is hosted by Ning.com, includes forums and chat, photo and video hosting, a music player, industry events, a jobs section, and integrated content from parent site Adrants. Users seeking to post videos and photos onto Facebook are able to do so with its app features.

The Wall Street Journal recently mentioned AdGabber in its observation of the rapidly-growing number of niche social networking sites. Adding to that, AdweekMedia launched its own social networking site for marketing and media professionals, called At the Roundtable, this week.
