Things are moving very quickly at AOL these days. Just a month after its announcement, the company has closed its acquisition of The Huffington Post.

Along with that announcement comes the addition of some more editorial staff,  including Senior Media Reporter Michael Calderone (coming from Yahoo), Senior Reporter Trymaine Lee (coming from the New York Times), Senior Congressional Reporter Michael McAuliff (coming from the New York Daily News),  Senior Political Reporter Jon Ward (coming from The Daily – interesting in itself, given how new The Daily is), Business Reporter Bonnie Kavoussi, and Entertainment Reporter Lucas Kavner.

When AOL announced the acquisition of The Huffington Post, it put Arianna Huffington in charge of all AOL content and started The Huffington Post Media Group to encompass all content from both The Hufffington Post and AOL. With that, it shouldn’t come as much of a surprise that there would be some people losing their jobs. Last week, AOL CEO Tim Armstrong said more layoffs will occur due to the acquisition of the Huffington Post, but that they’d “do it thoughtfully.”

“These new hires, which are only the beginning, demonstrate our commitment to great journalism,” said  Armstrong. “An outstanding team of talented editors, writers, and reporters — ranging from award-winning veterans to budding new journalism stars — will be at the heart of the Huffington Post Media Group. One of Arianna’s highest priorities is to build this first-class team across the many content areas covered by AOL and the Huffington Post, and to maximize the impact of their work on every platform, with great reader engagement.”

Since the  $315 million acquisition of The Huffington Post, AOL has lost President of AOL Media and Studios, David Eun and Executive Vice President, North American Sales, Mark Ellis, as well as a pair of editors at its popular tech blog Engadget.

News has also come out that AOL is buying hyperlocal blog service Outside.In to integrate with its Patch product.

It’s very interesting to see the progression of AOL over the last couple years. They have quickly gone from struggling Internet dinosaur (mostly conjuring up images of dial-up Internet connections and “you’ve got mail” sound bytes) to a high profile content company that seems to be dominating more and more of the web each month.

According to AOL, the combined entity of AOL and The Huffington Post will have a user base of 117 million unique visitors a month in the United States and 253 million around the world.
