From what I've seen on the subreddit, it looks like most cards are written in before they are sent, hence the need to ask for writing prompts. Personally, I find it's also nice to have blank cards. I can concentrate on enjoying the picture/artwork, and if I'd like, I can also pass it on to someone else to enjoy. It would also be less work, since the sender doesn't need to trouble themselves with writing a message. However, most card offers seem like they come written in - even if the sender doesn't ask for prompts, it seems to be implied. I feel as if I might be kind of defeating the purpose of the sub by asking for blank cards...

Would it be rude to request for blank cards? Do you ever send blank cards? How often do you receive blank cards?
