b2evolution Blog Engine

. For blogging newbies
You type something in a form and hit "blog this"; in the next second it's on your website page(s).
Pages are generated dynamically. Your posts are automatically arranged by date into a template/skin you have chosen and that you can customize. You can also browse through the archives and use advanced search capabilities.
Readers of your website can leave comments on your post that also get displayed automatically below your original text.

2. For average bloggers
b2evolution is a classy news/weblog tool (aka logware), i-e software allowing you to run newsfeeds and weblogs.
It does basically the same thing blogger.com and typepad.com do, but with two main differences:
It's free as free can be! (GNU General Public License)
It runs on your own domain/website. That means you need a host which can run web applications written in PHP. All the features you can expect are there, including:
Advanced browsing (paged, calendar, categories, search...);
Extended & multipaged posts;
Image/file upload;
Multiple and sub-categories;
Draft and quick publishing;
Spell checker;
RSS & Atom feeds;
Bookmarklet and sidebar blogging;
Blog with a desktop client (w.bloggar, etc...);
Automatic pinging of blog directories;
(more below...)

As you will find out, b2evolution also includes a lot more feature than the average blog tool. Check out the Features! b2evolution is a blog tool for blogger who want more!

3. For advanced bloggers
You could compare b2evolution to Movable Type, except b2evo runs on the vary common PHP/mySQL platform, which allows it to run easily on almost any web hosting service!
b2evolution also generates web pages dynamically from the MySQL database, so no clumsy 'rebuilding' is involved. It also means faster search/display capabilities, and the ability to serve your posts/news in different 'templates' or 'skins' without any hassle.
b2evo is probably the most comprehensive blog engine you could find, with an unique set of features including:
Simple installation;
Skin switching;
Localized in many languages;
Multilingual blogging;
Timezone handling;
Multiple blogs;
Web standards compliance with integrated XHTML checker;
Clean and search engine friendly permalinks;
User rights management;
Private/protected posts;

Trackback & feedback;
Integrated hitlogs and stats;
Anti-blogspam (referrer & comments);
Plug-in architecture;
Advanced rendering plug-ins (Textile, Auto-P, BBcode... );
