Email is currently one of the key elements of the Internet. And sending and receiving email is usually one of the first things we learn to do when going online for the first time. But its life could be coming to an end with new research predicting the demise of email within a decade. Its killers? Social networking sites such as Facebook and Twitter, and instant messaging apps such as Skype and MSN Live Messenger.

Twitter is a massively popular social networking and micro-blogging site that has gained an inordinate amount of headlines and copy over the past year or so. But what is the nature of Twitter? Is it for people to converse and share ideas, or is it for companies to try and connect with their customers and ultimately sell stuff? Stephen Fry, unsurprisingly, has an opinion on the matter.

Unfriend – to remove a contact on a social networking site – has been named the word of the year by staff from the New Oxford American Dictionary. Its editors say several tech-related words were considered for the honor.

Bullying has been around for generations and will likely remain a problem for generations to come. The problem is it evolves over time, with playground bullying first moving to mobile phones and email before seizing its chance to be inflicted via social networking sites such as Facebook and Twitter. But there are ways to prevent it and to stop yourself becoming a victim of abuse.

After a nearly flat September, Twitter saw a whopping 8 percent drop in users during the month of October. Has the service reached critical mass long before becoming mainstream?

Facebook has often played a part in getting people into trouble. But this is the first time that it’s been used to get someone out of trouble. It seems Facebook status updates are admissible as alibis.

Recent reports that a gang hacked into dozens of Facebook groups appear to be somewhat overplayed. Instead those involved have exploited a flaw in the way such groups work which could cause embarrassment rather than a security risk.

We have been hearing for years that technology tends to make people less social, replacing personal and non-virtual interaction with much less personal activities, but a new Pew poll says that may not be true.

The unstoppable juggernaut known as Facebook continues leaving a path of destruction in its wake as it adds even more users.

New York-based Peek Inc has launched a dedicated wireless device called the TwitterPeek meant entirely for tweeting on the go. However questions loom as to whether users need a device on top of their mobile phone to keep up with their tweets.

I’m sure the power of Twitter could be used for good. Unfortunately, at the moment it seems to be being used by adults to play some spectacularly childish games, with memories of the school playground flooding back as I read the latest tweets. Stephen Fry ended up not quitting Twitter and is back to normal. But the controversy surrounding comments made by one of his followers and the backlash immediately afterwards is rumbling on.

Twitter seems to be having a few problems holding on to its celebrity Tweeters of late. Lily Allen and Miley Cyrus have both quit recently, and Stephen Fry may be about to add his name to this list of Twitter quitters. The problem is that getting up close and personal with fans isn’t always a positive experience.

One of the most annoying things about Facebook is the amount of spammers attacking the social media site. As popularity in social communities rise, spammers have started to target these sites aggressively. One online marketer recently got slammed with a hefty suit awarding Facebook $711 million in damages.

The average Web user is a savvy individual who tends to err on the side of caution when surfing, sticking to trustworthy sites and only opening attachments to files they know are safe.

Luckily, the spammers and scammers don’t have it all their own way.

Want to write an application for LinkedIn that spreads between users or introduces people with similar interests? With those kinds of features closed, it’s no wonder that nobody is writing apps for LinkedIn.

Death comes to all of us in time. Unfortunately. And each and every one of us leaves behind friends and family who have to deal with the mourning process as best they can. What cannot help is having a constant reminder that someone is no longer with us on social networking sites such as Facebook. Which is why the idea of a memorial profile is such a good one – saving heartbreak and offering closure at the same time.
