Around noon today, I saw Scoble’s Twitter about Google’s purchase of Jaiku, and left two comments on his blog post. Basically, I said that Jaiku’s purchase made sense, but that Google probably considered Twitter and found Jaiku to be less expensive. I use both Twitter and Jaiku myself. I tried using Jaiku as my primary microblogging service, but came back to Twitter.

The thing about Jaiku is that it has more built-in features than Twitter, no questions about that. Its built-in feed integration service doesn’t even exist at Twitter, where we have to use the third-party Twitterfeed to get similar functionality. I wrote an in-depth comparison of Twitter and Jaiku back in July, and I invite you to have a look at it (see Part 1 and Part 2 of “The value of microblogging services”).

The kicker could be even more interesting though, and I don’t know if someone else has already touched on this. We all know about Facebook’s ridiculous $15 billion valuation, right? Well, Google’s purchase of Jaiku has just burst that absolutely ridiculous bubble. Jaiku offers functionality very similar to Facebook’s, but without all the annoying hype.

I bet you the price Google paid for Jaiku was very reasonable, much like the price they paid for FeedBurner. I for one am glad Google pays sane prices for their acquisitions, unlike Microsoft. The only time I think they splurged was with YouTube, but they paid for the users there. (They obviously didn’t pay for the content, since most of it was and still is pirated from TV and movies…)

I hope Facebook’s valuation drops down to some normal amount now, something like $500-750 million. By the way, I’m not on Facebook and I don’t intend to join it any time soon. I’m also not on MySpace.
