In an economy where social proof is becoming mandatory for media exposure and sales, cyber shills will be hired in greater numbers by brand and marketing firms, despite their public opposition to the practice.

SXSW offers many unique opportunities for those willing to plan ahead, take things with a gigantic grain of salt (with a side of BBQ) and ultimately enjoy the company of others who have figured out how to maximize their ROI: Return on Interactive.

Do you remember when female leaders at the top of Silicon Valley companies were hard to find? Well, they still are. But at least now, there are a few more than there were. Only 14 years ago Carly Fiorina was the first.

One can slice and dice the data in many ways, but there's no mistaking that 2012 was one of the best years for education technology in recent memory.

Hashtags corralled a legitimate, constructive conversation by multiple thousands into one space. The only way it could be accomplished was with hashtags. It was a victory for social media in an era when bringing partisan sides together in such a way is no small feat.

I have had a longstanding fear of straight lines. This is ironic because my life has followed quite a traditional linear trajectory: school... job... house... marriage... kids... grandchild. Can a line get any straighter than that? Yet, straight lines and my inability to draw them have long been a personal bugaboo.

The most important reason why I love my laptop is it opens the world to me without the need to leave the comfort of my home. When you have a disability, that's a very important reason.

This may sound a little absolutist, but at the end of the day, who is really controlling what you post online? Is that ironic music video your status because you actually enjoy it, or is it online because you want people to see how funny you are?

There are limits to how much technology can and should engage its users, however. We believe the next wave of truly useful services takes a different tactic: they let us focus on what's important by knowing more about us than ever.

How can you boost productivity so that you can maximize on your time? And at what point does all of this technology just get in the way of our work?

The "it's all about me" zeitgeist of pop culture clearly interferes with the development of both selflessness and empathy. Whether reality TV, hip-hop music, or violent movies or video games, pop culture's messages elevate the self above others.

Video may have killed the radio star, but free online music streaming services are putting the infamous Peer-to-Peer (P2P) music swiping services to rest. What is finally going to put the nail in the P2P business is not only free, but legal.
