I like that it is an easy way for us to quickly notify others about upcoming events at our office or with other companies we work with, without having to pay someone else's fee each time! It seems relatively good for my small business needs so far. There are not too many features but what they do offer works well enough for me. We use this service mainly just as another tool in building out social media presence of our organization; however there have been times when people don't receive notifications due to their email being marked SPAM/Bulkmailer instead of Junk Mail folder by Gmail. The benefit has definitely outweighed any downsides thus far. Adding event information into one centralized place makes coordination easier between different departments within my department (and hopefully across all organizations!).
