As a totally newbie in weblogging I started off with Pivot.
A disaster of 2 days work in/with Pivot,,, even theme-changing in firefox resulted in a bug in the posting. Continously rebuilding the files. There where one uses the GUI for writing articles and posting, seems like pivot sometimes forget some tags which results in a crashed frontpage look and some html verifying of the latest articles too look for the mistakes. Themes,,, so much more to find for WordPress, so after 1 day of install and putting back the previous articles ever written, I stay with WordPress
