An outsider's suggestion: I came to this article yesterday via the RFC. Without getting into the merits of various adds and deletes, I suggest that if folks see a need to cut a large chunk of text (and assuming it's not garden variety vandalism) they at least paste it to the talk page and critique it. That seems more consistent with the Wikipedia way.  
 

I see blogs are sourced and even comments posted by others to blogs. See Wikipedia:Reliable sources, especially  Wikipedia:Reliable sources#Self-published sources as secondary sources. In bold print, this is what what the Wikipedia guideline says:
""Personal websites, blogs, posts to Usenet or wikis, and other self-published or vanity publications should not be used as secondary sources.""
