I think illiteracy would be somewhat common in Equestria because most ponies won't need to use advanced technology due to magic being available and among those who are literate a large part can only read very simple texts and write short notes or their name. So if Twi saw that you can read a whole book and then talk with her about it that would immediately make her think of you as a potential partner.
