So far so good! Share InterNations Experience (Frankfurt)

Hello All! Although InterNations has been around for over 10 years servicing as a global social/professional network platform, it is new to me. So far my experience with interacting and socializing with the user community has been very good. I noticed that some city groups have a lot more interaction, groups or activities compared to others. I am curious if you have used InterNations for other cities, do you like InterNations and have you had a positive experience? Also what areas do you think could see improvement? Curious mind!
