Report: Plaxo to unveil social network on Monday

If two months' worth of perpetual hype and hearsay about Facebook have given you social-networking fatigue, it might be time to chug an energy drink--looks like we will see another serious entry into the field on Monday.

Launched by contact and schedule management service Plaxo, this will apparently be a sort of midpoint between the strictly business LinkedIn and the still-full-of-frat-party-photos Facebook.

The rumors started, as they often do, with a single blog post from a well-read blogger. After attending the "Lunch 2.0" event at Facebook's offices last week, Robert Scoble started up a minifirestorm of … Read more

Security researchers warn of LinkedIn exploit

Sometimes, it pays not to be linked in. Ignorance is bliss.

Security researchers are reporting a public exploit has been designed that could take advantage of critical security flaws in the LinkedIn Internet Explorer Toolbar.

The vulnerabilities do not apply to the Linkedin.com Web site, only the LinkedIn IE toolbar.

Users of the LinkedIn social-networking site that have the IE toolbar installed on their computers could be at risk of a remote attack, should they visit a malicious Web site, according to a posting by VDA Labs' Jared DeMott and Justin Seitz, who discovered the flaws.

The security flaws … Read more

LinkedIn reportedly jumping on the platform bandwagon

You've probably heard it by now--LinkedIn founder and chairman Reid Hoffman hinted to Dan Farber at our sister site ZDNet that within the next nine months, his site will be opening itself up to developers, Facebook-style. There's not a whole lot else to report now aside from speculation--and the speculation thus far has indeed been rampant.

This is especially interesting, because over the past few months I've seen a few trends: first, a more professional crowd gravitating toward Facebook; and second, that recent college graduates entering the work force haven't pounced on LinkedIn the way … Read more

Should LinkedIn do battle with Facebook?

Dan Farber, over at ZDNet, is reporting that LinkedIn's founder, Reid Hoffman, has made their plans clear to open up API's and create a developer platform. I am not exactly sure whether this means that developers will now be able to create applications, using LinkedIn's data to be displayed on their own site or if it will take the form of widgets on LinkedIn's own site like Facebook has done with their platform.

First off, let me make something clear. I do not think that LinkedIn can be the same type of social network that Facebook … Read more

Opening up APIs...LinkedIn goes "open source"

It's not open source, of course, but I find the gathering momentum toward opening up APIs in Web 2.0 applications to be an interesting spin on the "offline" open source world. First it was Facebook, and now it's LinkedIn. In the web world, it's not source code that gets opened (though these properties could do this and, in my mind, should), but rather APIs.

As to why companies are opening up the web, it has nothing to do with charity. It's actually very similar to the offline software world where you can put … Read more

LinkedIn rival Xing embarks upon a transatlantic trek

Here in the U.S., there's really only one big player in the sector of social networking sites geared toward professionals eager to make business connections: LinkedIn. Other business-oriented social networks have emerged, but none have shown signs of really eating into LinkedIn's stateside market share. That, however, is what Xing is trying to change.

Xing, formerly known as the less catchy OpenBC (BC stands for "Business Club") got its start in Germany and now boasts 1.69 million members. The company's moved beyond Germany largely through acquisitions and partnerships; when it expanded to Spain, … Read more

Highrise, a new app from 37signals

Yesterday 37signals founder Jason Fried posted about the team's upcoming contact management app called Highrise. The goal of the app is to help you manage contact information in a better way than relying on Post-its or your current software-based customer relationship management (CRM) tool. Think of it like a Rolodex but with collaboration and more space to write things down. Many people can have access to the same records at once, and from the announcement, 37signals thinks they can do better than your current CRM.

In many ways Highrise is a solution for a problem with Web communication technology: … Read more

Network with other travelers using PairUp

PairUp launched today at the Demo 07 conference. The service helps business travelers network with others going to the same event or locale. PairUp imports your Microsoft Outlook contacts, or you could also add them by name and e-mail address. You then enter basic trip information like hotel name, flight numbers, and the purpose of the visit, along with privacy options for how much of that information will be shared with others. When it finds connections with other PairUp users, it lets you know. From there you can contact those with similar travel plans and potentially save on shared expenses … Read more

My-Currency rates real estate pros

My-Currency.com, launching at Demo 07 on Thursday, is a complicated solution to a very simple problem: people can't tell if real estate agents are any good.

My-Currency is designed to bust through friends' recommendations and real-estate advertising campaigns in order to help you find the agents with the best knowledge of their market, as shown by how well they predict the outcomes of real estate transactions.

The site is built around a prediction market. It asks agents to predict how much properties will sell for. Agents "wager their reputation," and put in their predicted sales price … Read more
