It's easy to bike shed on naming and I don't really want to get into that.
I'd prefer we just settled on something and stick to it. However I will
offer some observations from the conversations we've been having on this

I like the abstraction of Blob away from File with File being a concrete
implementation of the Blob interface. I suspect going back to just File
adds a bunch of unnecessary things to the cases where the data isn't file
backed. It seems there are a proliferation of specs that reference the Blob
concept. In fact the confusion in my conversations with people over the
name has been about a Blob here being more like a Stream than what they
traditionally think of as a BLOB (with a url property for example). We
think using Blobs with XHR and IndexedDB, say, will become at least as
common as their use for reading files from the file system.
