É inegável: o WordPress é o maior CMS hoje em dia. Claro, existem os mais caros e inúteis, como o Vignette (agora chamado OpenText), mas ele é o maior simplesmente por que é aberto. Mas não é só por que ele é OpenSource que a galera não possa ganhar dinheiro desenvolvendo plugins para o WordPress. Aliás, na maioria das vezes é muito melhor você desembolsar uma grana e comprar um plugin (tirando as exceções), garantindo assim a segurança do seu site, das suas informações e se protegendo de futuras invasões. Abaixo seguem duas dezenas de plugins que podem melhorar a funcionalidade dos seus sites feitos em WordPress.
