From what i read in the article “what is web 2.0″ http://oreilly.com/web2/archive/what-is-web-20.html i can see many different advantages over web 1.0 . to me it can is like comparing a rotary phone to a cell phone, the options are endless. with 2.0 we can use our computer to communicate with many other users instantly, share files. have an endless source of resources that are updated by the user(Wikipedia) with 2.0 we can subscribe to rss feeds so it save us time on endless searches. 2.0 give us the capabilities to set our browser to our specifications etc, as a matter of fact the end user is what make 2.0 so great because we are the ones that put the data in it so it can analyze it and give us a more accurate meaning (open source software) with blogs we are able to communicate with others and share ideas on subjects that we are interested in without having to go to their website all we have to do is subscribe to their blog and we can see updates immediately.
with ajax and JavaScript web based applications can work like more like desktop applications.another advantage is democracy meaning the web is open to everyone and we all have the right to use all of its resource’s, we all have the right to change it, we are changing it, and i believe it’s for the better. i just hope web 3.0 doesnt take all this for granted
