Hi,
Great Post! I think your blog is great, but my opinion is not unbiased: I’m 40 & something ;).
I have a similar workflow. However instead of Hazel, I use a DT Folder Action: DT import & delete.
And because I don’t understand Dropzone’s concept of having the same folder in two places: within Dropzone (as a deletable pointer to the original folder) and outside it as an original folder, I use (the less sophisticated) Unclutter instead of Dropzone.
Cheers,
Jeff
