Partly a useful Blogging-Plugin. Because:
Uninstall doens't work properly. After using the main unistall button in the Backend Panel, it leave the imression that toe extensions is removed. But in the component folder "idoblog" keep remaining.
Somehow an email is sent from your domain mail client to the owner(if configured) mentioning the site, where the plugin has been used.
An additinal component for pointing out all the different categories would be a big plus.
Don't try using and pubishing Blogs for "registered users" only. I happens that it shows them anyway. No matter if it's marked for public or private reason. So a deep gap of security.
