Two stories came across my FriendFeed feed back-to-back this morning:
1. Compete: Facebook US Traffic Nearing Google, Yahoo – http://www.techcrunch.com/2009/06/09/compete-facebook-us-traffic-nearing-google-yahoo/ (via http://ff.im/3Lnxo)
2. Study shows only 10% of Twitter users tweets – Cnet Asia – http://asia.cnet.com/blogs/infochat/post.htm?id=63011357&scid=rvhm_ms (via http://ff.im/3Lnxh)
