When is there too much of a good thing?

So I am doing my homework this morning and I am realizing that I have 10 different windows open. I am searching articles, posting blogs, updating my wiki, checking my social bookmarks and yes even reading facebook every now and then for fun! This week we are learning about Ning, facebook and social bookmarks, and as a teacher I have to say it is both amazingly helpful and amazingly stressful to find the time to keep up with all of these sites! I do love technology and I am all in when it comes to technology in education. I also believe that it is amazing how much information can be shared between educators. I am just wondering at what point it will become so much that it will take away from my teaching??
