What are the advantages of sorting, sharing, and tagging web content this way? What are the disadvantages?
The advantages are it is organized in alphabetical order which makes easier to find and it keeps all records of the items one has gone through in the past.The disadvantage that there might be some privacy issues . One might not want everyone to look over one's shoulder of things on your list.

What do you hope to learn from CPL 2.0? I hope to achieve some basic skills in order to be comfortable with Blog/facebook etc.

You can probably guess from the title of my blogg that I am rather reluctant to enter into a unknown world of "blogging". My hope is to be free of fear about it and learn some skills in order for me to be comfortable with the process. Thank you Katie.
