Text File OR Word Document. What do you use for What?

Sorry for this stupid question, but I am having little trouble deciding when to use what format?For documents with lots of text meant for reading (Scripts, Letter, Blog Article) - I without question use Word Document.But for stuff like, My Personal lists (checklist, wishlist, short Ideas, other lists) I use Text file. But at the same time I can also use Word Document for them & format in Headlines, Bold.But Anyway I just can't decide between those two formats.What Format do you use for what? via /r/tech https://ift.tt/359UB0D
