On the other hand, there are some fun and engaging tools that can add something to a lesson. Tools like DoodlePoll or PollDaddy that let you get instantaneous usable feedback can bring a new dynamic to a class or lesson that you couldn't use before. A quick example I could use in the library is to create a poll that asks students what their favorite book genres are. If I've prepared book talks on a large number of books, this poll can help me with each class that comes in to focus on books that they are interested in instead of wasting both our times talking about something no one wants to read.
I also have to give a shout out to Weebly as I love it and use it for my personal site. I think on of the advantages of this is that it really is quick and easy website creation so any student can easily make a website and update it. You shouldn't have to waste time on the web-design piece and can jump right into a usable blog, e-portfolio or any other number of uses for a website.
