Its a great tool if you a serializing something - or you can somehow queue up your posts for the day (or year). There arent many metrics to go by - but 4pm and 10pm seem to be key times in whatever market you are trying to hit. This is the first tool of many... @contentjunkie and I are debating the next App to tag on (pretty sure its going to be some type of curation tool)..
Thanks for this post!
