Flex is now with 8 post formats built-in for blogging: standard, video, gallery, audio, link, quote, status and new “Custom” post format. With a bit of a code, you can insert module, iframe, HTML, or “Include Component” like Page Builder's page into your blog. Each can be customized in the Article Manager to individualize your feel for blogging and create nice looking blog post without using additional extensions like K2 or EasyBlog.
