I like how it can be used in so many ways for different businesses - from small local business marketing through out my city (and state) or even across states! It's very user friendly too which makes things easier when trying new features/tweaks as well if something goes wrong during implementation of feature updates etc..
The only thing i dislike about walls are sometimes there aren't enough options available depending upon what type event we're attending ebcause some vendors don;' t allow their products being displayed unless they pay extra money per month but then again not all companies do this therefore limiting our choices :( however once those issues get resolved everything works great :) Great product overall!! We've been able implement WALLS into multiple types oevents such us conferences &.
