Publicate is feature rich and packed with a lot of great ideas. Being able to curate and sync with a number of different curation sources is pretty sweet. Also being able to export curations to either email html or web html is really cool.
Publicate is the most robust of the tools out there, but tends to be stretched too thin. I have not seen any recent development improvements in a while, and the interface is a bit buggy from time to time, causing me to lose a lot of time focusing on formatting and working around the tool's nuances. I'd love to use this tool more, but for now, will wait to see if the dev team publishes any improvements/upgrades
