There is this service called ping.fm. Check it out if you havn’t heard of it. What it allows you to do is connect all your social media channels, and trust me it has them all, so that you can use one login to send your messages.
It even can segregate short messages from longer ones and post to different channels based on length. So for example a quick post may push to your twitter and Facebook status while longer messes may go to your blogger and wordpress blogs. Pretty cool stuff. It can save you a ton of time! It also can install on your mobile devices! Your welcome!
