For those who are developing their PLN or have decided to continue with what they have started. I think this article would be helpful especially it teaches you how to include a Youtube button on your website.
I was reading about PLN and comparing the tools online and i came across this blog that highlights the usage of Learnist in class which i thought would be interesting for those that may want to consider using it as a form of student engagement.
The other site that i would like to share is on the comparison between Diigo vs Pinterest. After reading the comparison it is clear that Pinterest is the better tool over Diigo in terms of visual presentation however there are some issues to consider when it is applied in a classroom setting. Hence i would think that this may be a tool more for personal use rather than instructional purpose.
