K2 Extension for Joomla is the newest blogging tool for the most popular CMS available today. For years Wordpress has had the commanding lead over everyone else when it comes to blogging. That however is about to change if more and more Joomla web developers are adopting this new platform.
Wordpress while extremely easy to use, is not very flexible in terms of site layout & customizations. On the other hand, Joomla is light years ahead of Wordpress in this regard. There are ways to have the best of both worlds by running both Joomla and Wordpress and have them serve the purposes for which they're best suited. The issues with these work-arounds are duplications of database and contents. Last but not least, your site will not look uniform because the blog section of the site will look different from the rest of the site due to Wordpress' theme.
K2 is not the first and will certainly not the last extension for Joomla to handle blogging, but it has shown tremendous potentials to be the tool of trade for this platform.
