If you’re on several social media networks, you might find that you have a hard time making sure that you’re connected to everyone you want across all of them. Or maybe you use Facebook more for leisure, LinkedIn more for business, and Twitter more for tossing around bon mots and coming up with really good hashtags.

Twitter recently announced a couple of applications that let you check your Facebook and LinkedIn friends and follow them on Twitter if they have accounts. Handy tools!

Well, handy tool at the moment — the Twitter blog post notes “The Facebook app cannot currently access your Facebook friend list. We believe this is an issue on Facebook’s end.” So let’s take a look at LinkedIn instead.

Log in to Twitter and LinkedIn, then visit http://tweets.linkedin.com/twitter. This app will walk you thorough getting a list of your LinkedIn contacts who are also on Twitter. In my case about half my LinkedIn contacts are also on Twitter, and about half of those I had was already following. You’ll get a list of your contacts, with a link to follow or unfollow each one (depending on their current status) and also with an option to make a Twitter list of your LinkedIn contacts. I had some concerns about this from a privacy perspective, but I see that the list this application generates defaults to a private one, so creating a list will not inadvertently expose your LinkedIn contact list.

A few minutes after browsing through these contacts I had a new list of several dozen LinkedIn contacts as a Twitter list. The LinkedIn/Twitter application does have an interface to view this list without leaving LinkedIn, but I didn’t like it — I didn’t feel that it was easy to read. So I took the list and put it in Hootsuite, where it’s a lot easier to go through.

I look forward to this application working for Facebook, but just the LinkedIn application pointed me to several people whom I did not know had a Twitter account.
