Community profile ability/feed

Could we implement a Retweet style function to post a comment to your profile wall (not necessarily back to the community again) but to be able to personalise your user profile with discussions and comments you think are of value to yourself and others I noted a comment from Shijun on a post yesterday that was really informative and useful, it would be a great function to be able to share this to my wall feed with other posts I think are of value to me and others who may follow me
