It will all be obsolete

I've been planning for a presentation\workshop that I am giving in October to the FAEA. The theme of the workshop is incorporating web 2.0 technologies in the art classroom. I began researching and planning for the workshop last February.
Some of the technologies I will be presenting I use regularly others not as often but I had prepared to present on all. I wanted to show the participants options on blogs, wikis and podcasts. As well as other ancillary web based tools.
Well in going over my presentation I have found that about a third of the sites\web tools that I had prepared for had already gone through significant changes.
This fact of web 2.0 (I use this term loosely to cover a very large and fluid group of tools I access via various electronic devices) changes and evolves at a progressively rapid pace.
So what you learn now will not be applicable a year from now. This makes this new media both very engaging and frustrating at the same time. PB Wiki has changed significantly 3 or 4 times in the year or so that I have been using it.
This creates an environment of continuous learning and I think that the workshop that I will be giving will have to reflect that fact. Participants coming to the workshop will be learning how to use the web to learn. They will find that some of the presentation I may have discovered only the night before while Twittering or reading over my blog feed.
This reminds me of the way very young children everything is new, exciting and they never know what to expect the next day. An adventure.
I hope no one wants a paper handout, I would have to bring a printer with me and print as the workshop was given. Even then it would not be current.
