Apologies if this is a slight derail, but it doesn't deserve it's own thread and is at least related.
Once you've gotten onto Smashwords' premium catalogue and are thus available at Barnes, Kobo, etc...do you bother specifically promoting those links, or do you still just promote your Amazon and Smashwords links?
I've just seen my book appear at the Kobo site, via Smashwords, but I don't know if I should bother shouting about it or not!
