The digital media can often be quick but less personal than the card rec'd personally or in the mail. It also becomes a keepsake - looked at years later when the digital versions of the same greeting, thank you or sentiment has long since been driven deep into the archives.
Lastly, if you want to really reach out personally but cannot do it through a face to face conversation - the note card creates a pause in life - a chance to say something to someone that you have put thought into and will be received as such.
