I have been reluctant to accept the Web 2.0 buzz but this list of Web 2.0 companies is a great way to get an overview of the space.

As the term Web 2.0 is pretty loosely defined it is hard to say who should be there and who not but at least this list gives you a wonderful overview if you are looking for nice applications to get things done on the web.

And btw we have launched a Web 2.0 Blog today - and we are looking for a Web 2.0 Guru who would like to entertain several thousand readers a day.
