Why did Michael Arrington agree to let AOL acquire TechCrunch? Ultimately, AOL's engineering power and its management team persuaded him to join the Internet company, Arrington wrote in a Wednesday blog post.

A reported price tag between $25 million and $40 million probably didn't hurt either. Who needs a JooJoo when you have that kind of cash?

Arrington first discussed a possible acquisition with AOL chief executive Tim Armstrong after an appearance at May's TechCrunch Disrupt event in New York. At the time, Arrington joked that he was half retired due to exhaustion, and Armstrong expressed disappointment because AOL would be interested in acquiring TechCrunch if Arrington stayed on, Arrington wrote.

Arrington clarified Wednesday that he was not tired of writing, but of dealing with technical issues - specifically finding engineers who wanted to stay with a company that primarily focused on writers. "AOL of course fixes that problem perfectly," Arrington wrote. "They run the largest blogging network in the world and if we sold to them we'd never have to worry about tech issues again."

Arrington also touted AOL's management team, though they are his new bosses. The TechCrunch sales team will remain, and the editorial focus of the tech blog will not change. "Tim told me that he doesn't want whatever makes TechCrunch special to go away," he wrote.

AOL also agreed to let TechCrunch be TechCrunch - if, for example, the blog got its hands on internal AOL documents like it did with Twitter last year, TechCrunch is free to publish those documents, Arrington said.

"The last thing we want to happen is to end up with same cuddly relationship that the Wall Street Journal has with its sister company MySpace, for example," Arrington said.

To that point, the Journal's Peter Kafka tweeted that, with a $30 million price tag, it appears "AOL values company that doesn't own content 2x more than one that makes it."

TechCrunch was actually just one of three acquisitions for AOL this week. The company also acquired online video platform 5min Media, and Thing Labs, which produces the Brizzly family of Web-based social software.
