R/W Web

Since the only thing I know of as a R/W was wikipedia (and to be honest I did not know that is what is called) Everything in the reading is new. All the tools are amazing and new. I am not sure if it is good that anyone can come along and put their data into something that I may be reading and not sure if it is real or not. I guess that just means one has to be very careful of what they believe.
Blogging I had heard of but never used. Never wanted to, never needed to. However, I wish now that I would have had this when I was an undergraduate so I could communicate with my professors this way instead of tests and papers. It is much better than the dreaded handwritten journal so the reading can be kept up with. I am sure I spent a small fortune in blue books when I could have just blogged the information. Wikis (wikipedia) being the one I have used, are great for quick info, links and some ridiculous information but I would never think to site this on any paper.
The interesting thing (both good and bad) is this has turned every person into an information carrier. Whether or not you have good info or bad info you are adding to something that will be read by hundreds maybe thousands of people. This is where the ability to change the information becomes good. It becomes all individuals responsibility to monitor the information. But this is my question. If there are little to no individuals that will approach someone on the streets and say "hey could you not use that language?" How many people are going to stop it on the Internet? Could this cause major problems?
Google docs is a real time online word processor. It allows an individual to write and post a piece online for people to read, critique and help edit your work. It is like an online study group or critique session. I have never even heard of this until now. So, of course I never used it. I would have. In college, my biggest problem was finding the time to go to the writing lab. With this you can do it at home while you are working on other things. My question would be the reliability. However, if you are inviting the people to your google doc I assume it would be people that you trusted and not just randoms. I think this is a pretty cool idea and holds a lot of potential for peer associated editing. This allows learning and teaching to occur at one time.
