New social media platforms have the tendency to bud, blossom and then pollinate with others. Continuing with this trend, Twitter recently announced that users will be able to display their tweets on Linkedin. This idea is by no means new. Facebook and Twitter have long been microblogging partners. But there is an interesting twist. Since Linkedin is a business social network, many users would rather their personal tweets stay off. To avoid potentially embarrassing gaffes, just add #in or #li to the business tweets and leave them off your updates about your cat’s latest antics.
