They mention some of the revolutionary promises like sharing information freely under the creative commons license, the easiness of sharing text, photos, video and audio materials via the web, communicating in real time through Voice over IP and teleconference-like tools, and the combination of mobile phone and the web (like I could blog by SMS from Ghana).
But maybe I like the pitfalls even better: (copied and shortened from their site):
- What to do when you’re away from the Internet? People that spend alot of time online begin to take it for granted - this was already the case before Web 2.0, but now new Web 2.0 services are encouraging you to do more online than ever. What do you do when you’re not near your Yahoo mailbox, your blog, your flickr account?
- Choose online services carefully. There are now a great many online communities, news portals, support forums, instant messaging providers, and advocacy sites that are serving every conceivable interest and perceived business need.
- A "stale" blog makes you look incompetent. Setting up a blog is quick and easy to do - but keeping it going takes perserverence, nurturing and planning. Many make the mistake of creating a blog, adding an optimistic launch post and then abandoning it forever.
- The web is forever. This may be hard to imagine, but thanks to sites like Google and the Wayback Machine, anything you add to blog websites or post to an e-mail mailing list might be retrievable even years later.
- Bad information is worse than no information. With a read-write web, any nutcase can set up a beautiful, legitimate-looking blog website and start posting falsehoods to the world.
I'd probably like to add that you still have to find people to whom it is useful to communicate and with whom you want to collaborate. You can easily waste your time writing a blog that nobody reads. And then I'd say the potential of the web is mostly in finding people who have dealt with likeminded problems as you, found innovative solutions, or finding people who are willing to think with you. So it needs a whole new skillset not to drown.
And with all this collaboration over the web- fighting over scarce resources will not diminuish. But maybe we can become smarter in using the resources? Yesterday I read about the Free studying through the internet (in Dutch) which is becoming a world wide trend. So people who are curious and want to learn (and are connected) can now really start self-learning. This is a huge shift.
