[xwiki-users] Is xwiki suitable as a blog now?

I'm still using XWiki 4.3 milestone 1 on my personal web server. It is not very useable as a blog since 1) very wide images aren't resized to fit the width of the blog 2) There don't seem to be pingback or other XXXbacks used to communicate with other blog articles. 3) For non-web devs or non-technical people, it is not easy to change themes or customize UI to make it look like a blog. The latest stable release is 5.1 now. Has it become useable for me?
