In the world of social media now, almost everything goes. Facebook it, Twitt it, Digg it, Blog it, come on come on come on!!! Here is my advice to you, businesses, individuals and anyone thinking of creating any of these medium.
News is, most people are only going to follow you on one of these networks, pick the ones that best suit you and suit your business needs do a great job at managing those, forget the rest unless you have loads of time that you have nothing to do with.
Blog First! A blog is a great way for you to communicate your daily events, news, articles, photos, editorials and more. But the best thing about the Blog is that, it can multifeed to Facebook, Twitter etc.
If you are going to pursue a business blog, please pay for one first of all (don't go with a generic freebee) and hire a professional to help you customize your look and feel so that is still professional and does not look like Joe's blog down the street. Professional.
Blog on topics of interest that tie into your business. Don't worry as much about keywords and optimizing text, think about what your readers, your customers want to know about. Answer their questions and explain ideas and concepts in your blog.
For example if you are a Wedding Planner or Wedding Event Venue, use this opportunity to show the reader what you can do, create and experience for them online with photos, commentary and more.
