Because of Google I/O, this was a momentous week for those of us who are watching the rapid transition that is taking place from desktop computing to mobile, and particularly for those focused on mobile-social as I am because of my job at just.me. Here is my take on what we just witnessed.

Standalone Hangouts. Google announced at its I/O event that Hangouts was to be launched as a separate app from Google Plus, taking personal conversations out from the G+ app and putting them into their own space.

It’s that time of the week for CrunchWeek, the show where a few of us writers chat up the most interesting stories from the past seven days.

Ryan Lawler, Drew Olanoff (clad in his Google Glass), and I discussed all things Google I/O, including Larry Page’s keynote, Google+’s new photo features, and the latest Google Glass apps and more. We also chatted about Square’s new hardware, Stand, which is a $299 card swiper and stand for iPad registers.

Tune in above for more!

Did Google’s conference succeed? It launched dozens of products and services in its 205-minute keynote, but did the world understand them? I saw some of the smartest journalists in technology struggling to handle the information density. But what’s the alternative? Break it up across multiple days, or even multiple conferences? Google’s breadth presents it with a challenge unique among the tech giants.

Apple? Its launches center around a discrete set of devices. That’s why WWDC works. There might be one radically new product, but then just a set of iterations on what we already know. The screen is bigger, the tablet is thinner, the software gets a new sheen. And since Apple is all about hardware you need to touch to believe, it has to do it all in-person. Journalists and pundits can easily digest the news and offer their insights to the world.

Facebook? It prefers the rolling thunder approach that works because it’s mostly a software company. Releasing things when they’re ready rather than waiting months for an event embodies its “move fast and break things” ideal. It reaches out to journalists almost daily about new updates. When it has something big, it throws a laser-focused, dedicated event like it did this year for content-specific news feeds, Graph Search, and Home. Even when it threw its last f8 developer conference 20 months ago, it kept it tight to just Timeline and Open Graph. The media could wrap its head around the social network’s plans.

It’s still practically a newborn but Indian mobile messaging app Hike is already channelling almost a billion messages a month between its five million registered users. Those numbers sound insignificant when you stack them up against the big beasts of the messaging space – WhatsApp claims 200 million+ monthly active users, and some 600 billion in and outbound messages – but Hike’s growth is  impressive when you consider it’s only just over four months old. WhatsApp, of course, has been around for almost four years.

Mobile messaging is hot property right now, with tech giants like Facebook and most recently Google bent on owning the messaging space. The reason for all this interest in cross-platform chit-chat is that mobile messaging looks poised to steal social networking’s crown jewels: aka the cool factor, and thus the user engagement (Hike incorporates social status updates and emoji-based moods into its messaging app, to hang on the social chain). But the idea that there can be one ultimate mobile messaging winner — or one player as dominant as Facebook in the full-fat social networking space — seems unlikely. And that’s what Hike is banking on to disrupt WhatsApp and keep Facebook Messenger and its ilk from crashing its just-getting-started party.

There’s no doubt that local market realities intercede much more on mobile than on the traditional social networking playground of the desktop, especially in emerging markets where device, network and carrier variations influence how people communicate based on how they can afford to communicate. Those complexities provide an opportunity for local app makers to triumph over goliath outsiders if they build fixes for the local market, argues Hike.

We at Overdose Caffeine had previously announced that Pocket Fleet, a real-time multiplayer space dogfight game developed for mobile devices, would be available soon on OUYA. Our players were looking forward to it. Even we were excited about the prospect of bringing the game to the platform, as we loved the device and thought TV was a great medium for fast-paced multiplayer gaming.

However, we have decided to end development for it and switch to GamePop. I know many people were looking forward to playing the game on OUYA, so I thought I’d explain why we made this decision.

Tumblr feels that Yahoo’s $1.1 billion offer as “too low” and view it as “only a first offer”, according to sources close to to acquisition talks. Yahoo may have to significantly increase the offer to close the deal. An acquisition by some tech giant is likely in the cards for Tumblr, though, as sources say the company only has a few months of cash runway left.

The news comes after AllThingsD reported Yahoo was in advanced talks to buy Tumblr for $1.1 billion cash, and the portal’s board of directors are set to meet on Sunday night to discuss the potential deal. Forbes reports that Facebook and Microsoft have also expressed interest in acquiring Tumblr. However, Forbes says that Yahoo has lock-up agreement arranged with Tumblr that prevents the blogging platform from holding a “bake-off” or bidding war for the right to buy it.

If Yahoo comes to the table with an insufficient offer, which our sources say $1.1 billion qualifies as, Tumblr may be able to reject it and shop itself around some more.
