I was recently asked by a reporter for resources on real, concrete events where blogging had a significant effect on political events, and while a number of events came to the top of my head (Trent Lott, Salam Pax, Ed Schrock, Bush's National Guard memos fisking) I was thinking it would be great to have a timeline for all of us - so I started one. It is pretty bare-bones for now, with entries for the aforementioned Lott, Schrock, and Rathergate. Please drop by and add/edit the page to fill out the timeline.
