Zho offers every kind of application one could need for accomplishing work at the office. It's pretty amazing that this is all free. I like that you can collaborate on docs in real time and that audience members can chat with the presenter Zoho Show. I tried LAST.fm and like it as a way to listen to all kinds of music, find information about musicians, network with others interested in your kind of music, and buy music (through Amazon). It's well-designed, easy to navigate, and fun to explore. I could sit here for days listening and learning and could easily get involved in networking. But alas I am too busy. Which is what I wonder about Web 2.0-where do people who are really into it find the time for all that networking and communicating? It is fun and worth doing, but there's so much going on in my life in the real world that demands attention.
