These days, it can be hard to keep track of all of your social networks. Hootsuite makes managing Facebook, Twitter and LinkedIn accounts much easier. It allows you to manage all of your accounts on these sites in one page.
If you want to send a status update, you easily select which accounts it will be broadcast to and write your message.
I particularly like Hootsuite for my Twitter accounts. I have personal account, one that I am just getting up and running for this blog, and I am responsible for two Twitter accounts at work (Spanish and English). Hootsuite lets me manage them all in one place without having to sign in and out repeatedly.
If sometimes social networking seems more like work than fun, give Hootsuite a try. It should make your life a little easier.
