Hi Moz
A slight misunderstanding here: what I meant was that the
majority of companies block social networking sites, but they (the sites) are now being identified as recruitment spaces, even if only by the minority. Poorly worded on my part: Apologies.
As for web 2.0, you are correct, there are many definitions and most people are unaware this term. As you said, "web 2.0? I didn't know there was a web 1.0!". I get the impression that you are aware of it, but for other readers of this post who may not, it generally refers to the increase levels of interactivity, with the user moving from passive reading to collaboration and involvement. As Stephen Fry put it, Web 2.0 is "an idea in people's heads rather than a reality. It’s actually an idea that the reciprocity between the user and the provider is what's emphasized. In other words, genuine interactivity if you like, simply because people can upload as well as download".

It is this interactivity that allows training applications. Trainee blogs (used as an online developmental diary) can become part of the assessment criteria. Students/trainees/learners (call them what you will) who are involved in distance education (or shift work) can collaborate on work via wikis; systems such as ustream and eluminate allow for presentations that participants can be involved in rather than being passive viewers. Sites like Ning allow individuals or organisations to establish "communities" which incorporate many features without needing extensive programming knowledge. Podcast allow the delivery of a variety of information, from training material to management memos, to staff who are not based "on site". Sites such as Second Life are being touted as "the next big thing" in training delivery by its advocates, especially since the introduction of speech capabilities (I'm not 100% sold on this theory, but will suspend judgement and watch what happens in this area with interest). Depending on your needs, there is more than likely something out there that could be of use.
Of course, I am biased, as I am involved in e-learning development. I do subscribe to the view that just because its new doesn't mean it is better, but also belive that just because its new, it shouldn't immediately be discounted. It all depends on how it is used: there needs to be purpose behind the use of the technology. "Because its there" is not a valid business case to justify its use. There was a time, in the not so distant past when it was believed that the net was just a passing fad, and there was little or no value in technologies such as message boards. (sweeping statement, but based on conversations held within my organisiation when we first moved into online delivery of training. At the time there was the on-line vs multi-media (cd based) debate going on).
Finally, I agree with you, I also do not see it as unreasonable for companies to block sites like FaceBook. As I said, it is primarily a time waster (from a corporate sense). My point was that there are other systems out there that are being tarred with the same brush that are of potential value.
The same could be said for general web access: jump on many of our manager's computers and look at the history bar in IE and you will invariably find the asx, realestate.com, or, during summer, "baggygreen.com" (cricket updates).
Like so many things, it’s the utilisation of the technologies that brings them into disrepute, not the technologies themselves.
Cheers
Lance.
