As we bring our Information Overload summit to a close, we have decided to name and rank the biggest culprits for the overload, the issues which more than anything else are causing companies to drown in a deluge of data.

Some of these problems have been around since the dawn of the computer age. Others are new, brought about by new technologies and different ways of working and servicing IT infrastructure. Nevertheless they all cut into the IT manager's time.

Managers are increasingly overloaded these days and the prevailing view is that they have more than enough on their plate without playing censor to an entire company. Yes, if someone's spending all their time looking at porn on the internet that's an issue for a company, but the prevailing view is that it's a problem in management, not in IT.

If a company is that worried about web management they should hire the services of a company like Websense to do the job for them, not force stretched IT departments to take up the role. The only time the IT department should get involved is after a complaint, either from someone on the floor who's spotted what's going on or from a manager who's concerned about lost productivity.

Shaun Nichols: The tasks of monitoring and managing web access has only become more difficult as interest in new web services has grown. Now, sites such as Twitter and Facebook aren't purely for consumers, and many companies also make use of them for promotion and customer relations.

This means that simply blocking everyone from these services is no longer possible, as they have become work tools.

At the same time, more and more new sites are popping up, more blogging platforms, social networks and casual gaming portals are emerging every day, making it far more difficult to keep up with what can and can't be blocked.

Then, on top of it all, there are the ever-growing ranks of malware infections and phishing scams connected to web applications and tools, making the risk of security breaches through the browser stronger than ever.

As such, the task of web management at the corporate level is becoming more complex and crucial at a most inopportune time.

We've all known at least one or two bosses and executives who love to throw about the latest buzzwords and demand that everyone adopt the latest business crazes, even if nobody is completely sure why they are doing so. Blogs, wikis and social networks are increasingly popular for companies as internal tools, and their implementation can be quite a task for IT staff, particularly when nobody is quite sure how they will be used.

The only reason that we haven't placed this issue higher on the list is because it isn't really IT's problem. Yes, setting up and managing those services takes a bit of time and effort, but the real issue is how those services will be used, and that is mainly the concern of executives, managers and end users.

Web 2.0 tools can be very valuable to a company, but they are only useful when implemented correctly and used to improve communication and collaboration. Really, it's far more a human issue than a technological one.

Iain Thomson: The growth of Web 2.0 has caused some additional headaches for IT managers, but it's not as bad as it could have been.

Because much of this content is user generated the demands on the IT manager's time aren't too onerous. It's setting up the systems in the first place that's the real time waster.

A lot of managers have also been rather smart about how they deploy such systems. Increasingly they will set them up, but in the spirit of user generated content they are tapping the users to police and edit such information. It's a smart move, and a logical one.
