Twitter created a bit of a stir late last week by cutting off LinkedIn. Ostensibly this was to project a consistent look and feel for tweets as the company adds features like threaded conversations, which LinkedIn didn’t convey. People who have accounts on both services will no longer have their tweets appear on their LinkedIn profile pages. It’s hard to know how much these updates will be missed on the business-minded network, which distinguishes itself by hosting a more focused conversation than “anything goes” Twitter. But the practical effect is that if you want to be heard in both places you’ll have to repeat yourself, unless you choose to do all your updates from LinkedIn, which still feeds one way to Twitter. More likely, you won’t because it’s too much of a bother.
