I've been using another blogging component on other sites for several years and decided to try out easyblog. Wow! What a difference. The interface and features are well thought out, the code makes sense and editing templates is logical. I submitted a request for a small feature and received a reply within an hour (along with an apology for "taking so long to reply")-- absolutely amazing.
Migration from other blog components is easy and built in so there isn't any reason for me not to migrate my other sites over to this. Social integration is simple and much of the component can be customized without touching code. Highly recommended.
