WordPress is certainly one of the most feature rich and user friendly publishing platforms available today. At the same time it is loved for its openness, extendability and great open source community. WordPress is today used in serious projects and on large commercial websites besides the millions of hard working bloggers sharing their valuable knowledge. This trend have created a huge market for professional high quality premium themes and recently we have also seen a market emerge for premium plugins as nearly any kind. Someone wrote a great article about it here: “35 Best WordPress Plugins” – http://www.tripwiremagazine.com/2011/12/best-wordpress-plugins.html
I will be posting more useful WordPress plugins soon. I have found quite a few I use, plus a few I’ve been developing myself.
