I like that it's easy for people who are new at using Twitter or don't know how to use hashtags effectively! It also has an option of adding your own hashtag so you can make sure everyone knows what you're talking about when posting something related to #OpenWebsuccessstory etc...
You could definitely get used to this app if you have been around twitter long enough but maybe not as many features compared to other apps out there? As someone without much experience in social media marketing/advertising we were looking into ways to help grow our followers which led us here after seeing some success stories posted by others through their accounts.
