Blog Writer - Write About Social Media and Other Interesting

Hi all, I'm looking for a fanatic internet/computer geek to do some blog writing. The blog is aimed to regular internet users who would like to get a little bit more out of the services they use online and also stay updated on the latest big news. So you would be posting about Facebook, Twitter, Linkedin, Foursquare, Tumblr, Angry Birds, Google+, etc... Mainly I'm looking for how-to posts. So you would give tips and instructions on how people can use different social media sites or maybe their internet browser more efficiently or just do some cool stuff. I'm not looking for quantity. I'm looking for quality. Maybe two posts per week. I want the posts to be in-depth, easy to follow and also include images where appropriate. Experice in Wordpress and basic image processing / graphics designing is a big plus but not necessary.
