I still find instant messaging over the phone too cumbersome. It works perfectly fine when it's one on one communication but when it comes to context switching it's just never as practical.

If anyone cracks a great idea on how to manage switching between convos on your cellphone in a slick way - please let me know!

Looking at one failed way of trying to "create virality" in an application by forcing the user to add it without giving any functionality on beforehand. The nudgemii application has quite a nice idea (being able to send mini-messages to a user's cellphone) but the way they publish it on the user's page before their friends have installed the app is really not that great.

Check it out to learn about some bad examples! We have been sneak starting our application "Reb me" now on Facebook, we'll be happy to have some feedback :)
