Which blogging software you think is better Nucleus CMS or Wordpress and why? I personally prefer Nucleus because its light only 600 KB but very effective, easy to install comparing to wordpress and much easy to use. It also comes with lots of plugins. Modifying skin is also very easy in Nucleus comparing to Wordpress or atleast I felt this way. But most important Nucleus support forum is much better than Wordpress. On Nucleus people are pretty happy to help you where on Wordpress people can be very rude.
I vote for wordpress to. It has so many features. You can do almost everything with wordpress. Not only a simple blog. Image, video galleries, and so on ... Wordpress rocks.
