The conversation bubble is interesting. It does apply to new media, particularly, social media. I would like to see other variations of shapes or design elements inside the bubble. What you have now is not really working for me. Think, connectedness, think people. #45 and #114 are working in this mode. You are on the right track with using a variation of the "im" Maybe try to go more abstract? And come up with something that communicates these things without being too literal or the same as other social media companies. The "people holding hands" design has been over played out. Thanks!
