The tool I saw today that I would most likely use is Fetchnotes. I am extremely comfortable with Twitter and have just started trying to keep a to-do list on my computer of tasks I need to complete. Currently, I use stickies, which is decent and gets the job does, but it is basically exactly like writing stuff down on a post-it note. Fetchnotes would allow me to stay organized in a more modern and technologically friendly way. I could use the app to jot down things to do on the go, which I can’t do now via stickies. I do agree that the ability to search other users is odd, because I’m not sure who wants to see notes that other people are jotting down. Who cares what someone’s to-do list is anyway? That seems like the most likely use for this app, but a social networking aspect doesn’t seem necessary.
