I just poofed the post, though I'm leaving the comments (strange, huh?) -- Squadratomagico makes an excellent point about overgeneralizing, and in retrospect, the post was written from a place of frustration. My apologies to any I offended.
In lieu of the original post, let me ask a question, in case people want to keep the discussion going: how do we, as researchers, weigh the relative value of years of work in the archives versus creative interpretation of the sources -- perhaps fewer sources, or perhaps working only from published sources? If you feel comfortable doing so, perhaps add the country you received your historical training in.
And I know many of my readers are stateside Americanists, so: do you think you work differently than your colleagues who study other countries? Do we medievalists just need to get over ourselves, already?
UPDATE: Fellow Blogger Tenthmedieval has left a very nice response (his second response, comment #17, I believe) in the comments -- I think it's well worth reading, so make sure to take a look.
