There are so many different blogging platforms out there, Blogger, Tumblr, Livejournal and many others. If you are running a WordPress Blog, it can be very easy to syndicate your blog entries to all the other blog services out there with simply one great add on. Virtually all services out there allow you to post your content via an email message. This makes it very easy to update your content on the fly from a smartphone. It also offers up the possibility for a WordPress plugin named Crosspress' to take advantage of this popular feature. It can be found here: http://wordpress.org/extend/plugins/crosspress/
Simply set it up, and add the posting email address to all the blogs or other services where you also want to post your current article. Just make sure to add a link back to your original article so that your original site will get the search engine credit.
Worried about Google penalizing your for duplicate content? Don't sweat it. Google understands that lots of people syndicate their blog and shouldn't get punished for it. To quote Google "Google will not penalize your content if it is found to be a duplicate copy of another web page and that's because even good websites syndicate content on the Internet. Make sure the copy links to your original article so that search engines can credit the right owner."
