StatusNet is the open-source microblogging platform that powers sites such as identi.ca, which impressed us from its inception as a "framework for a distributed network of federated microblogging services." Read on for more details on what Vibber will be doing there.

Vibber hard at work at the Wikimedia Foundation office.

And according to this StatusNet announcement, Vibber's job description will revolve around "architecture and development of the core StatusNet microblogging software, as well as ancillary services to support the status.net platform." And in addition to launching a first release and public signup over the next few months, it is hoped by StatusNet leadership that Vibber's "natural skills as a mentor and leader will help build our Open Source developer and user community."

Although Vibber's new duties will commence on October 12, he will continue to be involved in Wikimedia development and will remain in the Wikimedia office until the end of 2009 "to make sure all our tech staff has a chance to pick my brain as we smooth out the code review processes and make sure things are as well documented as I like to think they are," he wrote.

In an interesting study in open-source, free-as-in-freedom/free-as-in-beer cross-pollination, StatusNet founder Evan Prodromou is also known for his work in the wiki community, launching Wikitravel and helping with MediaWiki development.

As "volunteering" is defined as "working on behalf of others without being motivated by financial or material gain," this seems like a strange use of the word. In the case of employees deferring pay, this seems more like an unfortunate burden rather than an act of volunteerism. If you're an experienced professional looking to stay sharp and you've got the freedom to contribute to actual volunteer-driven efforts or you'd like to try working for a cause-based organization, below are some great resources:

2. Care 2: Care 2 claims to be the world's largest listing of jobs with socially responsible companies. The site offers a list of environmental and renewable-energy related jobs including positions for design and construction specialists with LEED certifications.

3. Idealist: Idealist is a project of Action Without Borders and lists a number of job and volunteer opportunities for those looking to become change agents. The site focuses specifically on addressing social and environmental problems and volunteers can do everything from building a shelter in Ghana to becoming a board member with a North American environmental agency.

4. Volunteer Match: San Francisco-based Volunteer Match helps almost 70,000 nonprofit organizations provide direct services and advocacy to our communities. Whether you're interested in driving a Meals on Wheels van or trekking to Nepal to rebuild structures of historical significance, Volunteer Match offers a variety of options.

5.Nonprofit Technology Network: NTEN is an extremely well-known group in the nonprofit world. Their annual conference draws some of the industry's best cause-tech experts including my personal favorite, Beth Kanter. The job site lists IT support, development and media director positions with great organizations across the country.

6. Opportunity Knocks: Opportunity Knocks is a great place to find jobs in the non-profit sector. The site allows users to narrow search results down by salary, city and cause-related interest. There's also a resume tool where users can upload multiple CVs and apply to jobs within the system.

7. Treehugger: Treehugger is one of the leading green networks and was acquired in 2007 by Discovery to help power their Planet Green channel. The site has always offered a variety of tips and articles on sustainable living, environmental justice and holistic health. The jobs site offers volunteer and paid positions for companies and organizations who've made a real commitment to sustainability.

8. NetSquared: While not specifically a volunteer or job site, NetSquared offers cause-tech innovators the opportunity to contribute to global solutions. The site issues challenges to tech-savvy innovators, and volunteers answer the challenges with mobile SMS aid solutions, social action map mash ups and Twitter fundraising tools.

9. YouTube's Video Volunteer Program: As a project of All For Good, the YouTube Video Volunteer Program matches budding filmmakers with NGO's that require promotional or educational video material. Some of the current project applicants include Alaska's Center for the Blind and Visually Impaired, Heart of America's Warriors and Earth.org's Open Travel Guide.
