#ThankfulThursdays are perfect for promoting company culture, thanking customers, and whatever else you'd like to be thankful for.
Reminders. Reminding yourself where you started in your small business is a wonderful starter post for Thankful Thursdays. People love soliloquies, especially if done by a big organization with a lot of heart.
Mementos. Show your appreciation with gifts. It's not always the kosher thing to do, but giving away free promotional items, swag bags, coupons, or trials helps your user base exponentially.
