I'm still sending about 10 cards every year to elderly relatives who are not computerized yet. In my condo there's nice custom - people who don't need still usable stuff can leave it on designated table in the lobby for others to pick it up and use. Few years ago after Christmas somebody left couple dozen cards with envelopes , I took them ensuring I have supply of cards for lifetime.
In my social circle we don't have habit of handing over cards to people we meet in person , handshake and hug are better.
I have Christmas lights on balcony for good 2 weeks already
