I just came back from a 10 day solo vacation to Europe. Rather than post updates on Facebook I sent postcards to close friends and family each day. It was a lot of fun taking time out of every day to go find a few nice postcards and send a handwritten note. I think the recipients really enjoyed it as well. I'm surprised postcards are around still-- but maybe they'll make a resurgence as people seek to rebuild stronger connections than social media facilitates.
