And while Microsoft has been making many online shoppers happy the past few days with the Bing Cashback system, Google has now set up a special ‘Checkout Deals’ page where you can get discounts on products purchased using Mountain View’s Internet payment system.

Savings range from $5 to $20 and involve hundreds of participating stores, including Buy.com, Petco and Toys”R”Us.

I’m left wondering why that Deals page wasn’t launched a week ago.

That second statistic is a little confusing. BillShrink basically means that if its users had signed up for the top matches generated by its cost cutting tools, they would have saved a total of $1 billion. Of course, not everyone who uses the service decides to change their cell phone carrier or credit card, so the total amount of money saved isn’t that high. That said, this is the first time BillShrink has disclosed the size of its userbase, and it’s clear that the site is getting some solid traction.

BillShrink has been gradually rolling out its cost saving services in new verticals over the last year and a half. The site kicked off with support for finding the cheapest cell phone plan in 2008. Since then it has expanded to include a service for picking the best credit card, saving money on gas, and choosing the best saving account or CD. Most users are interested in the wireless service though, in part because of a marketing push from T-Mobile, and also because dealing with hellish cell phone carriers is something nearly everyone has to do.

BillShrink is able to expand to new verticals relatively quickly because of the technology that’s working in the background. The site is essentially taking unstructured data from across the web and converting it into searchable structured data. That’s a feat that’s harder than it sounds — Google is trying it with Google Squared with mixed results. Granted, BillShrink is dealing with a smaller set of data than a search engine that can query any term, but the site’s backend is more tech-heavy than you might think.

Looking forward, CEO Peter Pham says that the site will be launching some new verticals next year, some of which will include major new partners. Pham says that BillShrink will likely be exploring the ‘Triple Play’ deals offered by cable companies for internet/cable/phone service, as well as a service looking at mortgages (a space that Google has recently entered).

Twitter has recently been criticized for exposing messages from users that have turned their accounts private – previously public messages remain indexable by search engines even after privacy settings have changed. Facebook is creating privacy controls, we’ve learned, that will allow users to set even previously public status updates to private, meaning search engines will be prohibited from indexing the content. It won’t be perfect, since anything published on the Internet is often spread far and wide. But it may allow users to hide previously public data to some extent. There are two big questions that remain unanswered at this point. First, what will Google’s response to the Bing announcements be? And second, is Bing paying for this data? Twitter is clearly counting on data streams as a revenue source, but our position has been that the data is simply too valuable to give to competitors. Why buy the cow when you can get the milk for free and all that.

Many have been innovative in serving people with directories. However, search has been long and hard especially that sometimes busts one’s mood. However, through the innovation of an online directory, one can easily find the number. Caller Wiki provides report of the number you dial. This will make sure that you are being directed to the right person or right company. By entering the numbers in the web, you can be given a report about the company, owners, and address of the phone number being searched.
