Every so often, you meet someone with a job title that makes you go, "Huh?" Either it's too technical to understand, too hard to describe or in some cases, people just may not have heard of it. But, why would someone not have heard about a job existing?

Simple: All the changes that have come about the past 10 years, from environmental policy to emerging technologies to the recession, have all contributed to careers surfacing that never could have existed before.

"I've noticed that the best of breed iPhone apps incorporate Twitter and social networks, and the best Twitter apps seem to be on iPhone," Sagolla says. "That is no coincidence: The two came to prominence at roughly the same time. I've worked hard to position myself at intersection of those two industries, which form a vortex of attention and zeal that is unmatched."

Here is a little information about 10 careers that didn't exist a decade ago:

1. Bloggers

What they do: Bloggers research and write blog posts in a conversational style to engage readers online. They work for themselves or for corporations, but their goal is the same: to develop and maintain blogs to promote a brand, mission or objective. Jimmy Moore, owner of "Livin La Vida Low-Carb," started his blog in April 2005 after losing 180 lbs. He wrote about it while still employed in a customer service position. He began blogging full time in October 2006.

2. Community managers or content managers

What they do: Community or content managers are an extension of a typical marketing role, but on a more personal level. They serve as a face between the company and the public, managing a site that allows them to engage with current or potential community members, or spread the word about the company.

Erin Bury has been the community manager at Sprouter for almost one year. She says, "A community manager is a non-traditional role, so it requires some unique traits: the ability to adapt quickly, the ability to juggle a multitude of tasks while still keeping a smile on their face, and an innate passion for what they do. This isn't a 9-to-5 job; it's one that involves being an extension of the brand almost 24/7, which is why loving the company and the job is a prerequisite."

3. Green funeral directors

What they do: Green funeral directors incorporate environmentally friendly options to meet the needs of families who want a green service.

"A green funeral may include any or all of the following basic options: no embalming or embalming with formaldehyde-free products; the use of sustainable biodegradable clothing, shroud or casket; using recycled paper products, locally-grown organic flowers, organic food; carpooling; arranging a small memorial gathering in a natural setting; [or a] natural or green burial," says Elizabeth Fournier, a funeral home owner who works as a green mortician. "It's a fabulous opening for an individual who is green-minded in all aspects of their work."

4. Interior redesigners

What they do: Instead of spending $500 on a new couch, why not use that money to hire an interior redesigner who will find new ways to decorate with items you already own? Interior redesigners remodel your home using the things you already have, either repurposing them for other uses or putting them in other rooms, etc.

Jennifer Schweikert, owner of Just My Style by JMS, says, "In a time of 'less is more,' people streamlining possessions, baby boomers and seniors downsizing, and the green movement of reduce, reuse and recycle, interior redesign is an up-and-coming field of work that addresses these needs in today's lifestyle and economy."

5. Patient advocates

What they do: There are several types of patient advocates and although their services vary, all of them want to make sure that the patient and family is informed, and makes things easier on everyone. Advocates can go with patients to appointments; ensure they're visiting with the right specialists and taking the right medicines; sort through medical bills and negotiate fees with health-care providers and insurance companies; they can even educate family members on proper care for their sick loved one.

5.Senior move management

What they do: Senior move management companies help older adults and families with the physical and emotional demands of downsizing, relocating or modifying their homes.

6. Social media strategists

What they do: Social media strategists use social media tools for companies, creating and maintaining an effective social media strategy by interacting with users, growing brand awareness, creating buzz, increasing traffic and providing valuable information.

8. User experience analyst

What they do: The nuts and bolts of a user experience analyst are that they look for ways to make the experience on a Web site easier, more pleasant and more engaging for consumers. They want to figure out how to keep you on their site and how to make your experience while you're there memorable and useful.

9. Video journalists

What they do: In the 1960s, reporters had to shoot and edit their own stories because of lack of manpower and resources. Now, almost 50 years later, this role is back, but now it's called video journalism. To save money, large market news groups hire small market reporters as video journalists at a fraction of the cost. They are usually assigned stories to produce for the station Web site, finding content to drive Web traffic.

10. Virtual business service providers

What they do: Many people are starting to form their own companies by way of telecommuting, offering such virtual services as customer service, concierge or even public relations from their own homes.

"Thanks to the birth of the Internet and the rise of new industries because of it, my company was born. The rise of virtual companies like ours has provided jobs for lots of people," says Deborah Sittig, owner of Green Room Public Relations.
