I think sending "thank you" notes to someone is rare because it's a bit odd to contact a complete stranger and thank them. Personally I would "thank" someone for example by upvoting their post, commenting on it, or posting their project here or on Lobster, staring their GitHub project, etc. Those are more concrete stuff and personally I would appreciate this kind of actions more than a thank you note.
