Could the social group-buying space get any frothier?

Well, yes, it could.

After the recent $135 million funding of Groupon that valued the Chicago start-up at upwards of an eye-popping $1 billion, rival LivingSocial announced to today that it had raised a more modest $14 million in a Series C round.

The Washington, D.C. start-up had raised $25 million in a Series B venture financing only a month ago. And it raised $10 million on top of that since 2008.

Sources estimated the valuation for LivingSocial is several hundred million dollars now.

The newest round was led by Lightspeed Venture Partners; Earlier investors U.S. Venture Partners, Grotech Ventures and Steve Case’s Revolution are also participating.

Ironically, Case’s former No. 2 at AOL (AOL), Ted Leonsis has been an early investor in Groupon.

LivingSocial said it will use the new pile of cash to expand to dozens of new markets, adding it was launching four new cities now: Portland, Orange County, Charlotte and Philadelphia.

It now operates in 18 cities across the country.

For those in Silicon Valley who do not consider these prices for all these social e-commerce sites high at all, BoomTown is here to tell you that in the real world the figure is not actually modest, except in comparison.

But LivingSocial will need every penny if it is to compete with Groupon and a growing spate of competitors in the local space, much as is also happening in the social status update arena.

The local outcome for most will inevitably be a sale to a big Internet company like Amazon (AMZN).

Or oblivion, especially since so many similar offerings makes the whole market confusing for both local businesses and customers

In general, most offer a daily deal with a huge discount on a wide range of products and services–from spas to skydiving–in dozens of U.S. cities, for large groups of potential buyers on the Web, through email or via social networking sites like Facebook and Twitter.

Using social tools, the idea is use collective buying power to get low prices and push customers to local businesses.

If a deal reaches the number of buyers it needs, which can be in the thousands, these services sell vouchers to the consumers and collect a hefty fee for the sale from the businesses it sends customers to.

The plus for many small businesses is to get a crack at a lot of new consumers–think of it as social networking lead-generation.

This kind of thing has been tried before, of course, centering on consumers who group together to get discounts on items by purchasing in bulk.

In Web 1.0, there were many group-buying sites, most of which failed badly. One of the more high-profile ones, Mercata, received $90 million in funding from investors, including Paul Allen’s Vulcan Ventures.

No matter in 2010!

That’s due to the VC frenzy going on, spurred by winner-take-all theories–Groupon, for example, got most of its recent mountain of cash from champion Russian overspenders, Digital Sky Technologies.

However it turns out, here is LivingSocial’s official press release:

Because of the rapid growth, and high user demand, LivingSocial will use the capital infusion to expand into additional markets–bringing Deals to dozens more cities throughout the U.S. in 2010. This additional funding comes on the heels of the company’s recent $25 million Series B round announced last month.

“We’ve known and admired the LivingSocial team for a long time, and I have bought many of their terrific local offers. They’ve done an excellent job of growing their user base through smart media buying and excellent knowledge of social channels and virality,” said Jeremy Liew, managing director of Lightspeed Venture Partners. “With this financing round, LivingSocial is very well positioned to bring their great offers to even more people.”

By signing up for LivingSocial’s free daily online service, people are saving an average of 50-70% at their favorite places, such as the hottest local restaurants, spas, sporting events, hotels, and other local attractions.

Hyperlocal deals not only help more consumers explore new things in their city, but these deals also provide merchants with a greater opportunity to reach local audiences on the LivingSocial Deals platform.

LivingSocial is now live in 18 markets including: Washington, D.C., New York City, Boston, Atlanta, Austin, Seattle, San Francisco, Los Angeles, the Twin Cities, Chicago, Raleigh Durham, Denver, San Diego, the San Fernando Valley, Portland, Orange County, Charlotte and Philadelphia.
