Utterz, a service that lets you post multimedia to blogs and social networks from your mobile phone, has expanded its service to 17 new countries.

The company has also introduced new online video and audio capture, and “conversational threading” capabilities to help users engage and connect with friends, followers and social groups, both online and offline.

Podcasting & Blogging Support

Utterz’ new online Webcam and PC microphone recording lets users create a podcast or videocast in minutes. Utterz audio files are distributed using RSS 2.0 and include basic ID3 information tags, transforming even the most basic of mobile phones into a podcasting platform.

Utterz Connection lets you selectively post multimedia Utters to pages on any of the major blogging platforms or to social network pages with Utterz widgets.

“With Utterz I can update my WordPress and five Blogger blogs as well as my Twitter and Flickr accounts in just seconds,” said Drew Bennett, author of The BenSpark and The WiredKayaker blogs. “And since I can update each one or all at the same time, from anywhere, I post more frequently than I normally would and with more interesting content.”
