Google buzz and other social timelines

Ryan commented that my google buzz has multiples ofthe same post but slightly different form. My guess is that it is pulling the status post and blogs from various output and feeds from my other website apps and rss feeds. Since my contacts aren't into google buzz I guess I don't have to care much about sorting it. My main concern is more on my main social websites like facebook where I need to avoid double posting. As for twitter, well frankly with its short microblogs it shouldn't be too much of an issue for double post, but I try to keep it to a minimum.
