thanks for this, but if so, may I know what IP.blog is mainly for on your plan?
For us, we have a forum and try to encourage members to use Blog embedded to gain stickness
If blog is not comparable, why they will use this? This is a very serious and "practical" question
If you sit down and think about how the two are used it becomes a little more apparent.
When a user goes out and signs up for a Wordpress blog, it is an individual blog. He is the owner, he is the author. He runs the blog, which is the whole site in this instance. As such it is a natural order that he should be able to control it's finer details: the layout, the content on the blog, and so forth.
IP.Blog is a community blogging system. While we try to, for the natural sake of familiarity and conformity, give members a little place all their own when they create a blog (i.e. the newly introduced themes feature, the custom headers that can be auto-generated, and the content blocks), it is still a blog created within a defined community. The general idea would be that the blog would have something to do with the community, or be a part of the community.
The member does not own the site, you do. As such, there is a fine balance that must be struck between what a member can do and what a member can't do. For instance, different admins want a member to control a layout to different extents. They may want a member to change the font color for instance, but not change the background color. They may want a member to have full control over the look, rather than just be able to control aspects of the look. And there is always the issue of security....this is a very critical and difficult thing to take into consideration when you are giving members this sort of control. On your own blog, you're not going to hack your own site. When you allow members to create and customize a blog on YOUR site however, it's easily possible a hacker could register and put nefarious content into CSS or content blocks (if javascript were allowed) that could damage your entire site.
As such, there are different goals and different considerations that are taken into account. In a Wordpress blog, the user owns the entire site - in IP.Blog, the user owns a very small piece of a larger site, and this makes all the difference in the goals.
