It seemed to save it, then after the crash, the post was gone. I suspect the browser session was already corrupt, and the post did not register on the site. The crash also took my draft since like a damm idiot I had not manually saved, but was letting it autosave as I was writing from the top of my head and therefore too busy to bother. Only one at blame here is me for not doing with I tell folk to do on a daily basis- save often!
