Productivity Tools - key word is productivity
I checked out nearly all of the productivity tools mentioned. I guess that it is beneficial to know about them from a technology literacy standpoint, but I do not see them being of much use. The web based Office type stuff, I don't see the point. I guess that if you were stuck doing something from a library, or on vacation in Europe you might need to resort to them, but otherwise nearly every computer that you use to access these will already have MS Office on it. Some of the other ones seem of trivial value, that could be more easily accomplished by email than setting up these types of file sharing or polling etc. I use UMCal, but I guess that I don't see myself using many others of these.
