I like that it's free! It is easy enough anyone who has an internet connection could use this service without any training whatsoever (as long as they have facebook/twitter). The interface isn't very intuitive which makes me think there are some features missing from whiz wifi but i'm not sure what those would be yet because we haven't used them much. We're using this mainly just so people know about our business when walking by if one of us happens to walk out front while someone else answers phones etc..
