Choosing a social tool

I feel like the research of three technologies is taking a lot longer than I had anticipated. I have spent most of the weekend reading, looking at, and setting up different accounts on social sites to trial. I have found that there are many more out there to be discovered, but I have to keep reminding myself only to research three.It is quite easy to get absorbed into the technological world and get carried away with your research. I need to focus on the task. Today, I checked back over the marking rubric for Task 1: social learner,  to make sure that I was addressing all the criteria. 

What I need to do from here: 

• Decide on the most appropriate.
• Give a detailed description of the technology I have selected and its features.
• Create my social Space.
• Produce PDF instructions for my peers.
