If you’re not familiar with twitter, yammer and twitter are similar to bloging but you only have about 150 characters to write about. The interesting part about yammer is that it is a mix between twitter and linkedin. Yammer is business oriented. Now I am not sure if you are able to “follow” other people outside of your business but it’s only another thing to keep up with and to play with.
I have added my yammer profile link to the left. See you there!
