I have posted this question elsewhere as well--

I am looking to start a web-based business that involves building a community. I am trying to come up to speed on all the technologies (content management systems, software as a service, Web 2.0, etc.) so I can be involved in making technology choices, working with a web design/development company.

Where can I get a reasonably good view of the current state of the web, and a discussion of these new terms? I am looking for an downloadable document, or a buy that I can buy.

Thanks all!

You might want to start with this Wikipedia entry. Coverage on the 2008 Web 2.0 expo here. Be sure to check out the various links, and you might want to consider attending in 2009. Here's a good Web 2.0 strategy guide.

Thank you vingogly for the very useful links! I bought and read the strategy guide. It had good discussions on flickr, Google and some of the economic underpinnings of web 2.0.

Appreciate your help.

You're welcome! :)
