I like that we can easily set up our own network by choosing people from different departments in order make it more personalized! It helps us communicate better within my organization as well across organizations which makes life easier when working remotely or collaborating internally/externally at any time day / night without worrying about who's online next door etc..
The only thing i dislike now would be an easy way out if someone drops off your community (for whatever reason). This has happened few times but since its not always possible there are other ways around this issue such as moving them into another team where they will have similar interests again so you don't lose their interest completely - even though sometimes some members do dropout after awhile because things change fast nowadays especially over internet connection issues due too many users being connected all together making connections laggy during peak hours.
