Wordpress started as a blogging system but has evolved into a full content management system with plugins and widgets. It is an open-source project developed by hundreds of contributors worldwide, offering more customization and flexibility than most commercial platforms. Wordpress focuses on user experience, web standards, and stability as a mature product after launching in 2003. Slideshare allows users to share presentations, documents, and videos to build knowledge and grow their business within the largest online community for presentation sharing. Blogger offers a blogging site where users can create blogs linked to their Google account, insert images and videos, and follow other bloggers without advertisements.
