Over the last six months, doubleTwist, the iTunes alternative that lets you manage your music, videos, and photos, has really been stepping up its game. In October the company integrated an Amazon-powered MP3 store, allowing users to download and sync their music directly with any of hundreds of compatible devices, much as they would with the iTunes/iPod combo. And today it's adding a new feature that makes it an even more viable iTunes competitor: support for podcasts. Co-founder Monique Farantzos says that doubleTwist has built and integrated a podcast search engine with 20 times as many podcasts as iTunes offers. Rankings are based on popularity (as opposed to a simple listing that would grow unmanageable with that much content). The new feature is launching on Windows now, with Mac support for podcasts coming next month.

Since it launched last July at our Realtime Stream CrunchUp, Brizzly has been one of the best web-based Twitter apps. It offers support for viewing pictures inline, shortened link expansion, multiple Twitter accounts, and even some Facebook support. But they've been quiet in recent months. Now we know why. The Brizzly team went into hibernation because they made a couple of acquisitions, and have been working on a new feature. First, they bought one of my favorite Twitter iPhone apps, Birdfeed. One of the earliest apps to gain Twitter geolocation support, I had been worrying that Birdfeed would go extinct because developer Buzz Andersen recently joined Jack Dorsey's mobile payment startup, Square. But since the acquisition (which actually occurred in the November/December timeframe), Andersen has been working closely with the Brizzly team to wrap the app in its new skin.

Earlier this year, Google landed a "landmark" deal with Global Cricket Ventures, the licensing partner to the Indian Premier League (IPL), which would give them the so rights to live stream cricket matches from the IPL on YouTube. This is a huge deal because the streaming of the 2010 IPL season (which starts on Friday and lasts for 45 days) is the first time a large-scale global sporting event will be streamed; with the reach expected to be at least a half-a-billion viewers. Now of of India's largest gaming companies, Indiagames, has bought the official gaming rights to the IPL tournament to deliver games around the Indian cricket tournament. Indiagames will be launching a series of web and mobile apps throughout the next 45 days. The first app, called IPL Indiagames T20 Fever, is an online game that uses Facebook Connect to allow users to create cricket teams consisting of both Facebook friends and IPL professional cricketers. The game will also include micro-transaction support, allowing users to users to virtually buy IPL players to improve their chances of becoming the IPL Champion.

Regular readers will know my love for all things location. In particular, these check-in location-based services fascinate me, mainly because I see them as a bridge between social networks as we've known it, and actual social interaction in the real world. Foursquare has been my app of choice over the past year (it launched almost exactly a year ago at SXSW). But the latest version of Gowalla has me thinking about switching sides. At the very least, I'll be using both at all times now. Gowalla version 2.0 for the iPhone just hit the App Store today. With it, you'll notice a few different things. First and foremost, the overall look has been updated from a sort of Army green, to a more subtle light green that is much easier on the eyes. More significantly, the toolbar has been reworked so that now social activity is front and center when you load the app, while your own activity is the last tab. Both of these changes are things I've complained about since day one with Gowalla, so they're certainly welcome. But that's not why I'm excited for the app. I'm excited because it takes the idea of the check-in and extends it.

Sonos, the Santa Barbara, California based startup that develops of wireless multi-room music systems, is taking a new round of financing from London-based Index Ventures, we've heard from multiple sources. Partner Mike Volpi, a forcer Cisco exec who found himself in the middle of a huge drama last year around eBay's Skype spinoff, will join the board of directors of Sonos. Volpi will bring real expertise to the Sonos board. As recently as 2007 he ran an $11 billion routing and access products busines for Cisco. He clearly knows how to sell products at scale. Sonos has been around since 2003 and has raised some $40 million from private angel investors and BV Capital. Until last year the company sold very high end music products that users loved passionately, but the mutli-thousand dollar price point for a complete system made mainstream penetration difficult.
