I keep 2 Evernote accounts, one personal, one business. Some reasons/tactics: - I don't want my personal documents to show up whenever I'm showing a coworker something and do an Evernote search. - I only have my personal account active on my smartphone. - I share 1 folder between my personal and work accounts.. this is helpful if I take a picture with my smartphone and need to send it to my work account. - If I leave my job in the future, I'll surrender my work Evernote account to my employer as to not keep confidential information.. it's a bit harder if I have personal and work accounts mixed.
