Josh Holmes from SRT Solutions gave a lively overview of the data binding and caching options in ASP.NET 1, 1.1, and 2.0. He pointed out excellent pros and cons of the technologies, when to use them, and which options to aviod (e.g. never flush from cache). He used the example of the "world's dumbest clock" to illustrate the different levels of caching that can occur. Josh is an excellent teacher, and has recently been inducted to the INETA Speakers Bureau.
