Zynga added a 600-plus-pages addendum to its IPO filing yesterday and it turns out that Zynga and Facebook are intertwined so tightly that it is hard to tell where one company ends and the other starts. The best example is two agreements that the companies came to in May and December of 2010 that reveal the depths of the Zynga/Facebook relationship. What it boils down to is that Zynga and Facebook work so closely together that Zynga might as well be the official game-maker for Facebook. Yet, that is not the case nor will it be. It makes one wonder why Zynga is bothering to go public at all as opposed to just being subsumed as a division within Facebook.

The Federal Bureau of Investigation has raided the homes of over a dozen alleged "hacktivists" associated with Anonymous in New York, New Jersey, Florida and California this morning, according to Fox News. The main Anonymous Twitter accounts, the group's primary mode of communication with the world, have been silent but a correlated account @ThaiAnonymous has weighed in on the raids.

"It doesnt matter how many people the 'FBI' arrest.. wether they are core members or not.. #anonymous have started something unstoppable."

Anonymous and related hacker group LulzSec have angered governments across the United States and Europse in recent weeks with an "AntiSec" campaign designed to attack government agencies and contractors. It was just a matter of time before the FBI tracked some members down.

Apple released the iPhone app for Google's red hot social network, Google Plus, on the iTunes store this morning. (link) Enthusiastic Plus users appear very excited to take advantage of the native app, which offers features like photo uploading, Huddle conversations and push notifications - in addition to the features already offered by the mobile web interface.

Unfortunately, the app has a lot of shortcomings. Most of those shortcomings are true of Plus's Android App as well, but the fact that Google had to wait three weeks for Apple to approve the Plus app couldn't have helped the development cycle relative to early feedback on Android.

Last Fall I wrote about Geoloqi, a bootstrapped geolocation platform that points to where I hope location technology will go in the future. The service offers an app and today launches an API that uses persistent location tracking to trigger notifications tied to real-world places. Maybe it's a note you or a family member left for you at the grocery store or maybe it's part of a set of geolocated data that you opt-into subscribing to as a layer because it was of interest to you. Some users use Geoloqi, the company says, to let their co-workers know how quickly they are getting through traffic to arrive at work. The company also announced that it has raised investment capital.

Location tracking is likely to become a part of all kinds of mobile apps and there's a world of potential in the technology - from lifelong education to augmented commerce.

A Google Plus account by Your Anon News, a part of the hacktivist collective Anonymous, was banned from that social network as having content that violated Google's community standards, according to Time magazine's Techland blog. Your Anon New's Google profile and Gmail was also cancelled.

Now, Anonymous has announced its intention of creating its own social network, AnonPlus.

Real estate service provider Move, owner of Realtor.com and related sites, announced this morning that it has acquired SocialBios. SocialBios is the startup named the most promising new technology at the prominent annual Inman real estate industry event this year. SocialBios is a service that aggregates a realtor's social profiles from around the Web, displays their updates, finds out which friends or interests they have in common with potential real estate clients and more.

What does social media mean for real estate? I spoke with Errol Samuelson, president of Realtor.com, last week and he said he thinks substantial disruption of the industry is possible.

Amazon unveiled a Kindle Textbook Rental, giving students the ability to rent instead of buy digital textbooks. Amazon says that, "tens of thousands" of titles from some of the major textbook publishers - including John WIley & Sons, Wlsevier, and Taylor & Francis - will be available for this school year.

It's not just the selection that the company is touting, of course, it's the savings: "now students can save up to 80% off its textbook list prices by renting from the Kindle Store." Amazon's boasted savings for students has put the company at odds with brick-and-mortar college bookstores, and the National Association of College Stores has accused the online retailer of misleading students about the potential for savings when buying textbooks from Amazon.

Well, it's finally here. After two years of delay and a fresh $100 million round of funding, European music streaming service Spotify launched in the United States yesterday, much to the delight of music geeks, a handful of celebrities and pretty much everyone on Twitter.

In addition to a whole lot of excitement, Spotify has brought with it a number of questions. What does this mean for the future of music consumption? Will artists make money? Perhaps most importantly, is its business model sustainable?

Should photographers be concerned about Google Plus? This is the subject on an ongoing debate right now, due to the wording Google uses in its Terms of Service - specifically parts that seem to indicate it will have rights to photos posted on the new social network. But some folks, including both professional photographers and an intellectual property attorney say the reaction is overblown. The issue is not a "Google" problem - it's something to consider before posting your images online, anywhere on the Web.

This week, the lawyers at stock photography leader Getty Images have decided to weigh in on the situation, too, as it relates to the company's Flickr Collection contributors. Getty's verdict? "We're OK with Google+," it says.

Google announced its second quarter earnings today and the numbers are a significant reversal from the slight dip the company saw in Q1. Google's gross revenue was $9.03 billion, more than what investors had projected.

CEO Larry Page kicked off the earnings conference call and described not only the financial data but some other notable figures as well: the number of Google Plus users, how much they're sharing, how widely Chrome has been adopted and the current activation rate for Android devices.
