What prompted my suggestion are some recent comments about the “Three Red Lines” imposed by 科学网编辑部. This thought actually occurred to me when I witnessed two “wars” since mid September 2009 when I joined the net.
I think we need another button to allow Bloggers (with Blog accounts) to vote DOWN a particular 博文, as implied by 王志明 (to sink “bad” Blogs below the surface). Each Blogger can only cast one vote on a particular 博文 when he thinks it is destructive to the net. When the total counter hits a threshold, say 50, that 博文 “vanishes” from the front page of the net.
Once again, many thanks to 科学网编辑部! Your service is greatly appreciated.
