Seth Godin offers a sequel to his ebook, aptly titled: "Who's There?"

Who's There is not an ebook about how to write better or how to follow the traditional conventions about formatting and building a blog. It's not designed to sell you one service instead of another, either.

Instead, I divide the blog world into three groups and turn my attention to one. And in particular, I try to sell you hard on how building a blog asset can have a spectacular impact on you, your career, your organization and your ideas.

Barron's writes about MobiTV and GoTV:

MobiTV, which is operated by Idetic of Berkeley, Calif., basically is providing a live, streaming feed of popular broadcast and cable channels (some on-demand programming is available too).

GoTV Networks, based in Sherman Oaks, Calif., not far from the studios' back lots in Burbank, provides specially packaged "on-demand" versions of your favorite programs and networks. Both companies' services can be watched on dozens of PDAs and mobile phones with color screens. Naturally, the more advanced the screen, software and chips, the better the quality of the picture. A JPEG chip -- a special microprocessor designed for video -- is often a key ingredient to better viewing on the hardware side.

Without any disrespect for either company, MobiTV strikes me as more of a Silicon Valley technology company, and GoTV as more of a Hollywood media company. Curiously, one of the first things both companies pointed out is that they have Emmy Awards on their sides -- MobiTV for its technology, and GoTV for producers and technical talent. All that's missing is Joan Rivers and the red carpet.

Jeff Jarvis has suggestions.

The goal is to be ready — God help us — for the next disaster so people can better use the internet — via any device — to better:
1. share information,
2. report and act on calls for help,
3. coordinate relief,
4. connect the missing,
5. provide connections for such necessities as housing and jobs,
6. match charitable assets to needs,
7. get people connected to this and the world sooner.

Russell Buckley speculates:

Let me give a scenario, in maybe 10 years time.

You're out shopping, with your mobile phone, obviously. Your mobile has taken over as your primary means of making all voice calls - using Google Net's VoIP, naturally. Why would you use anything else, when it's free and works everywhere? You don't even have to search for a good connection like those old GSM phones.

Your phone has also become your primary means of accessing the internet, again via Google Net, obviously. Your phone is a thin client, with most storage and processing done on the web. Most people don't have even a PC anymore. If they want to do work that involves a keyboard and a bigger screen, they just pop their phone into the nearest docking station and away they go. With the added advantage that the phone has ensured that the screen layout, favourite apps, bookmarks and files are all available exactly as you'd want them.

Your phone also knows your location at all times - not through anything fancy, like Assisted GPS, but because Google Net knows exactly where you are on the Google Grid.

So suddenly, true location based marketing becomes a reality, no longer a question like "when the tech is available" or "providing you're in line of sight" or "if it's accurate enough".

Forbes wrote about the potential importance of Google Talk: “By distributing the program, Google could also cash in on its core business of helping Internet users find information, selling advertising space on those search results. Ultimately, Google could charge advertisers extra for a "call me" button, providing consumers with a direct link to call a business they find in a search. Imagine searching on Google for details about a local restaurant and calling for reservations without leaving your search results page… The true promise of Google Talk --and the company's likely goal--is to eventually provide full telephone capabilities, and to make a user's Gmail address their primary point of contact, on or offline…By using the same identifying name for several different kinds of communication, Google hopes to put itself at the center of all of its customer's communications.”

Phil Windley builds on the concept of Identity: “Google's strategy is based on becoming the Internet OS and integrating commodity components (i.e. Linux, OS X, and Windows). Google can't build an integration point without an identity strategy and their identity strategy has to include synchronous messaging and presence–things they get in spades and on the cheap from a IM system built on XMPP.”

The Pondering Primate wrote about Google’s decision to link a Gmail ID with the user’s mobile number:

Looking closer at Google's Talk, I realize they are in the process of dominating the mobile space as well. One of the ways to get GoogleTalk is is if you have Gmail (or are invited for a Gmail account).

Now you can get a Gmail account AND GoogleTalk if you just give Google your mobile number. What a smart way to not only to get people to sign up, but to get a mobile phone number database.

Things I see Google does with this if they create a mobile messenger.

Google would have a permanent search window on your mobile for search, IM, or VOIP.

Google SMS would be incorporated into this search window.

Google would keep track of all of your mobile search requests in your Gmail that you could review later on the big screen.

See an interesting product and want more info? Type in the barcode or take a picture and send to Google SMS. Get info back on the product and that info is stored in your Gmail account under "Things I Mobile Googled Today".

Would you download a Google toolbar for your mobile? Instead of going to www.google.com, you had a little search box that you could type a search query in.

What if that search window incorporated GPS into your search query?

What would Google have to offer you, to make this part of your mobile screen?

Do you see where this is going? When you agree to download this mobile toolbar, you have given Google (and their clients) permission to advertise to you.

Think of taking Google's keyword revenue model and DOUBLING IT by offering a mobile version.
