Although the popularity of some Facebook apps has been shaken up since the redesign, allowing for others to emerge, Facebook apps in general are still booming.

Revolution Money is an online payment company owned by AOL co-founder Steve Case.

SpiralFrog hasn’t been doing so well, but $2 million can heal a lot of wounds, and the ad-supported, Web-based music service has raised this amount in funding.

It may or may not be time to use the r-word, but even in a recession, money has to go somewhere, and $10 million has just found its way to Kosmix, the vertical search company.

In several areas, Google’s the hands-down, for-the-foreseeable-future winner in America.  But in China, that’s not the case, and so a new $20 million investment in video-sharing site 56.com seems like a decent use of money.

If we’re heading towards (or already in) a recession, it isn’t yet hurting online advertising much – AdBrite, which specializes in that field, just received $23 million in funding.

There’s seems to be some small, subtle thing that keeps Google from succeeding in China.  Unfortunately, I can’t identify it (the ability to do that is probably worth a lot of money).  But as further proof of its existence, a Chinese YouTube clone just received $25 million in funding.

In a series B round of funding, the Indiana 21st Century Research and Technology Fund showed its confidence in ChaCha by tossing in $2 million.  Morton Meyerson must really like ChaCha, though – he gave the human-powered search company $8 million.

So what if the real estate market is tanking?  I think that’s much more interesting to read about than a break-even or everybody-gets-rich scenario, and some investors may feel the same way; Curbed.com, a blog that covers real estate, just received $1.5 million in funding.

It would have been more fitting (in terms of alliteration) if FiveRuns had gotten around $5 million in funding.  Instead, the company, which works with Ruby on Rails, did especially well and took in $6.2 million.

It’s not quite ready to overtake Blogger or TypePad – from which it claims to be completely different – but Tumblr, a blogging company, is now $750,000 richer thanks to a round of funding.

SocialMedia Networks is behind several Facebook applications, including FoodFight.  FoodFight allows users to “throw” various things, including piles of poop, at each other.  Fortunately, this app’s success is not directly responsible for SocialMedia’s recent $3.5 million round of funding.

Some beta services are more refined than others, and TokBox, which offers free video chat, may still have a ways to go.  But TokBox has the support of Sequoia Capital, and also has around $4 million from the venture capital firm.

Many of you may have heard that Matthew Aslett is over at The 451 Group now.

$8 million might buy thousands of newspaper ads, or perhaps three or so Super Bowl commercials.  But in this case, the $8 million will go towards funding Turn, the self-proclaimed “world’s first automatic targeting ad network.”

Waterfront Media sounds big, and it is – properties like EverydayHealth.com receive millions of visits per month.  Waterfront Media is also big in a financial sense, and a new round of funding brought it $25 million more.

As funding rounds go, this was a big one: Zillow raised a fresh $30 million.  Look for the already-popular real estate site to really take off as a result.

In the world of video-sharing sites, we see competitor after competitor that is, when you get right down to it, “not YouTube.”  But for car people, there’s something that’s even better, and it just received $6.1 million in funding.
