I was definitely surprised at the number 1 being twitter for learning. This might be because I hadn't had a twitter before this class so I do not know much about it. I can see why google docs, youtube, powerpoint and google are the next leaders. I use those on an eery week basis. I was surprised though that Wikipedia was at 18. It is not a reliable source but I guess for quick and dirty information, it is an ok site to use. I would definitely not for a research paper or anything like that though. I assume facebook is used for learning because it helps people stay current with the newspapers pages on everyones news feeds. There are also current events in the news that pop up all the time on my feed. I have heard of linkedIn and that it is a good network builder but I have to look further into it. I use 7 out of the top 10 on a regular basis so I would say this list is pretty accurate for me. I did not know I used so many of them already (probably around 30-40 of the top 100)
