Is this finally the year that my clients rise up all at once and demand that their applications have Web 2.0 features? There's been a lot of hype surrounding Web 2.0...richer GUI's, happier clients, etc. However, it wasn't until recently that I actually had a client give me a request to implement a rich GUI. I'm going to build it using Flex 2.0, which I'm told makes building Web 2.0 applications very easy. I just find it interesting that I've just had a client request something like this. I usually just use the same old libraries and my clients have always been quite pleased with that. Looks like I'm going to have to start building some new ones.
