I have been using ilo since the initial beta stage and I absolutely love it. The analytics are more accurate than Twitter's own analytics platform (for example, Twitter's saying that I haven't posted any tweets in September which is inaccurate) and the layout is neat and easy to get around. Having seen the evolution of the platform through the beta stage, I have high hopes for the product. It'll be a treasure trove for anyone who wants to grow their Twitter presence and the marketers out there, helping you understand more about your top content and plan the content and growth game.
Congrats on the launch, @dr !
