An interesting issue arising from people's use of Web 2.0 applications like Twitter, Facebook and social networks is that casual or informal learning has now become embedded in people's working lives. In the past, there was a fairly clear division between the kind of learning you experienced by chatting with colleagues in the staffroom or watching a TV programme on the one hand, and going on a course (usually for a day or a series of evenings) on the other. Recording the former never really came into it, and recording the latter is fairly straightforward: you just need to decide how you're going to do so, as discussed in a 5 Minute Tip on the subject.

But the landscape has changed now. Many people, myself included, tend to either have a stream of tweets constantly going on in the background, using 3rd party tools like Tweetdeck, or make a point of checking their Twitter stream, Facebook messages and so on at certain points during the day. Given that on most occasions you are bound to see a message containing information that is likely to prove useful, I think it's legitimate to regard these tools as an integral part of one's professional development. If so, the question is, how can you record that for the purpose of being able to complete the part of an application form which asks what training courses you've been on, or what professional development you've had, over the last X years.

Having given this a lot of thought over the years, I've come to the conclusion that recording professional development in the Web 2.0 sphere is not possible in the same way it is when recording ordinary training courses. If you were to note down every useful tweet or message, or even simply the dates on which you received useful tweets, you would give yourself a nervous breakdown and cause the person reading your application form to die of boredom.

It seems to me that the best way of recording, and proving, professional development in the Web 2.0 world is as follows:

If you go to a conference seminar, like the ones at the BETT Show,you can usually pick up a certificate of attendance. Do so.
If you 'attend' an online discussion, such as the Classroom 2.0 Live talk I spoke at ask the organisers for proof of your attendance (the Classroom Live folk do this automatically if you indicate that you'd like it).
Record your attendance at such events as the ones described so far.
Keep a weekly journal listing, in broad terms, the things you've learnt or come across that week. This can be in the form of a blog or eportfolio, as suggested by Andy Hutt and Ray Tolley respectively in response to the 5 Minute Tip already referred to, or as annotated social bookmarks (which may be able to be set up to appear on a blog automatically).
Ensure that somewhere in the application form you make it known that you're a member of such networks and therefore have a rich and varied informal learning experience.

Bottom line: I think it's important to bear in mind that what the application reader is looking for is not likely to be a list of every single professional development opportunity you've taken advantage of -- which could mitigate against you if you give the impression that you never have time to do any actual work. They're almost certainly looking for evidence that you're up-to-date with developments in your subject area, and that you know what's going on and what the issues are.
