I work in journalism/social media but I still send postcards, and letters. I use emoticons but send thank-you notes.
8 things that pique my interest (well more than 8):
• Journalism and the news (it's my job and I love it)
• Books (and figuring out if they're going to be around... short answer yes, but...)
• A nerdy sports fan... so more into wacky stories and history of sports than stats.
• Food and stories about food. I cook fairly often and I like to feed my friends...
• Sometimes a snappy dresser, decent cook and knows how to iron his own shirts.
• Indie music
• Booze (Craft Beer and well-mixed cocktails... although I'm comfortable bending elbows at a dive bar drinking a beer and/or having a pickleback)
