Twitter is trending with the promoted hashtag #AmexSync. Do you get annoyed with the “deals” that your Facebook friends “like” showing up in your newsfeed? Well prepare for it to get even worse on Twitter, as American Express and Twitter introduce Amex Sync, the service that connects your American Express credit card directly to your Twitter account.
