This was a fun challenge. I enjoy blogging and it is a great way to start a discussion on anything you want. It could be a way to talk with family and friends on a regular basis or it could be a great way to "vent" about something to the world and get input from others.
Google docs and spreadsheets was the hardest for me to set up and I'm not sure if I would use it personally. Depends on the nature of the document I guess and if needed, I could use it in the workplace.
I enjoyed YouTube the most because of the awesome content that you can find. Forget the political banter from the Democrats, give me funny TV shows anyday! I am going to explore this further to find things I haven't seen in a long time.
All of these tools are beneficial to PVLD. We already use blogs for communication and Flickr to post photos from various events. I think the staff who opted to do this challenge will continue to go back and test these 2.0s more and more. I think staff who didn't want to do this or didn't have time to do this should try to explore some of the tasks. They will be surprised by what they find.
