Which free blogging platform should I use? Blogger, WordPress.com, Tumblr or another?
blogger and wordpress are the nice one
WordPress is one of the best because there are not hidden costs and is totally open source. You can also find loads of themes both free and premium. Great themes are also found on Themeforest.net which are premium. WordPress.org
WordPress is till number one blogging paltform in the world!
I prefer blogspot over wordpress for its simplicity.
Bear in mind the kind of audience your blog will be aimed at, as well as the format of the posts. If you want to reach a younger audience, for example, Tumblr would be a good choice.
Blogger may be easier for new users, but WordPress is more advanced. Blogger allows ads, but WordPress doesn't. Tumblr, on the other hand, is more of a 'microblogging' system.
WordPress if you want a real blog. Tumblr if you only want to post pictures, videos and quotes.
Osama that totally depends on whats your aim? if you want to start a simple, free, quick setup blog and easy to customize then blogger should be your priority. And if you want a community based or more professional website type blog and can afford investment then there's nothing better than WORDPRESS and last TUBLR is a CMS (Content Management System). So rather searching for try all of them and then select the one that best suits you.
