How much technology is too much?

Is there too much of "the department of redundancy department" in technology tools? If I use Wikis, do I need Groups and Blogs? If I'm on Facebook, do I also need MySpace? With a plethora of choices for many different applications, we have to be judicial with our time and use of tech tools. In this era of adolescent obesity, how much do we want to invite our students to spend even more time sitting on their hind ends in front of a computer? While I value the tools I use for my students' access and communication, I also want to focus on providing them with choices that will encourage movement, activity and creativity. How will this look? I'm not sure yet, but will surely be considering it.
