I like collecting QSL cards - partly because this is the final confirmation of a QSO implemented. But I collect these too because the motives and layouts on a card are often very nice, and in some cases they can also tell you about the place and the person or the radio club behind a callsign.
Then, some diplomas that you can apply for today still require a paper QSL card to confirming a contact.
But I think this requirement is likely to decrease in the near future and be replaced by various digital solutions such as eQSL.cc or LoTW etc.
Changing and reducing the administration of a diploma would be a good solution in many cases.
But I hope the QSL cards wont disappear completely in the future because I think they actually mean something - at least that's the way for me.
