This is hilarious
for, as usual, my timing is more than serendipitous: I uninstalled the Nook app from my phone just last night due to the fact that I hadn't logged in for years, and although I kept the app installed for some [potential] ePub reading it actually miserably failed for this task when I tried it for the first time yesterday. So, out it went.
Any of my data potentially still on B&N's servers is probably close to 6+ years old, I don't think I've even logged on since then if not longer. In order words, so stale as to be useless, all my personal business data has changed since then.
