I like that it's very easy to use with no programming required! It has all of our event information in one place which makes managing everything much easier than if we had each site set up individually (which would be too time consuming). The interface could look better but other then this there isn't anything really bad about using livewall - just make sure you're getting what your paying for because they do charge quite heavily per month compared to competitors products/services out their such as Eventbrite & Meetrics. We used them at an internal conference last year where everyone was able post tweets from various hashtags related to topics being discussed during different sessions throughout the day- so people were tweeting away while simultaneously seeing who else attended certain talks etc..
