Thank you totallybogus, the greaterwrong site is exactly what I was looking for. It might be a good idea to have this site linked somewhere from profile pages so users can see how to reach these archives.
Habryka, the load more option does not provide any practical way of getting to stuff older than a few dozen posts, and does not have any way to get a link to a given range of posts to allow you to return without again trying to load the entire history a few posts at a time through the load more option. It would be a very nice addition to either provide a way to search by date range, or a link to the greaterwrong site that does provide easy access to older posts.
Hit a broken link: https://www.lesswrong.com/user/Eliezer_Yudkowsky/submitted/?count=117&before=t3_17j. This is from a page of chronological post history, clicking on the "Prev" link at http://lesswrong.com/user/Eliezer_Yudkowsky/submitted/?count=128&before=t3_14r.
It also appears that there is no way on the new site to browse chronological post history by a specific author. If LessWrong no longer supports this, is there any alternate site for accessing Eliezer's historical posts, or is everything that is not part of a sequence lost? This is an unfortunate step, as Eliezer's writings were a valuable resource for helping people learn rationality, and limiting access to them seems like a poor idea. Please restore some way to browse post history chronologically, preferably in a way where specific time frames can be loaded.
