Various senior scholar-type people have occasionally told me, "Oh, you should really ask [random established senior scholar I've never met] to take a look at your book manuscript. It's probably right up her alley."
I've never been sure whether this is intended as advice, exactly, or how to implement that advice if it is; sometimes there's an appended "you can mention my name," but more often it seems like well-intentioned free-associating: huh! you work on this stuff! it sounds like that stuff that so-and-so works on!
So tell me, O internets: is this something that people actually do--contact established scholars they don't know and ask them to read a goddamn 220-page manuscript? I'm having a hard enough time working up the nerve to ask people I sorta know, and who have been kind in the past, to do such a thing.
