SlideShare, the online presentation property of professional social network LinkedIn, today released a new feature called Send Tracker to help presentation makers determine which of their slides are the most effective.

LinkedIn purchased SlideShare in May 2012. The online deck-hosting tool, only partially integrated with LinkedIn, accounts for 39 million monthly unique visitors, or 25 percent of LinkedIn's total monthly unique audience. SlideShare is also at the center of the public company's strategy to become a hub for professional content.

Send Tracker, a new tool for users who pay to use SlideShare, is specifically tailored toward marketers, salespeople, … Read more

If Instagram and Vine had a baby, they'd name it PhotoBlab. This free iPhone app lets you create and share short photo slideshows with audio.

After launching the app and signing up for an account with an e-mail address, the app will ask you to add a profile picture or you can choose to do this later via settings. At the bottom of the app are four buttons: Create Blab, Blab Feed, Popular Blabs, and Settings.

You can get some PhotoBlabbing ideas by browsing the Popular feed, while the Blab Feed lets you view so-called Blabs you've sent … Read more

Recently, cloud-storage service Box was offering free 25GB accounts to new customers.

I meant to write it up, but other things got in the way. Good thing, too, because now Box is offering free 50GB accounts to new customers. My foot-dragging is your gain.

Before I go any further, take note that the signup page says "Dell Exclusive Offer." There's no indication you need to actually be a Dell customer or employee or anything like that, but there's always the chance Box will get flooded with unintended/unwanted sign-ups and decide to end or even rescind … Read more

Market researcher Canalys has again put Apple in top spot among PC makers with an overwhelming 20 percent market share.

Apple shipped 27 million units in the fourth quarter, while HP and Lenovo both shipped around 15 million (HP slightly more than Lenovo), putting them in the No. 2 and No. 3 spots, respectively.

Samsung is also on the rise: it made an appearance in the top five for the first time, pushing Dell out of fourth place.

All of this is possible because Canalys counts "pads," i.e., tablets, as PCs -- not a ludicrous concept considering … Read more

As Apple appears to be winning the U.S. smartphone race, Google still has a strong hold as the top mobile platform.

Running out of space on your hard drive? Hey, even in these days of seemingly endless gigabytes, it happens.

Bitcasa is a new service that aims to supplant your hard drive with unlimited cloud storage. And by supplant I mean replace -- kind of.

I'll circle back on that in a minute. For now, consider this: a year of Bitcasa no-limit storage normally runs $99, but right now you can get a year of Bitcasa Infinite for $69. If that doesn't immediately butter your bacon, how about a 10GB Bitcasa account absolutely free?

Update: As eagle-eyed reader brotherj2k … Read more

New mobile browsers including Google's Chrome, Microsoft's IE, and Amazon's Silk are gaining a foothold in a market that's growing faster than traditional browsing on personal computers.

The mobile browsing market has long been dominated by three products. Apple's Safari has long held the top spot in usage share measurements by Net Applications, with second place going to Google's unbranded Android browser after it surpassed Opera Mini last year.

Safari had 61.0 percent, the Android browser 21.5 percent, and Opera Mini 9.8 percent of usage in January, measurements released today show. … Read more

Thousands of legitimate files are being blocked and removed from users' Mega accounts, even when the file is legal for sharing, according to a report.

TorrentFreak tested the situation, uploading a number of files free for sharing, including, amusingly, a video explaining fair use and a copy of Mega founder Kim DotCom's own music single. All were removed within minutes, with TorrentFreak receiving e-mails from Mega explaining that a take-down notice had been issued on the files.

The problem is that Kim DotCom recently took to Twitter to claim that Mega was receiving only 50 copyright take-down notices a … Read more
