personally i dont like facebook. I see its purpose. I believe that it naturally leads to static relationships that are not necessarily based on commonality but something else (obligation, family, creepy kid at school) whatever im not hating its a good way to keep in touch with friends. I think that for people who activily participate in any type of group activity, a social networking app/site that would put you in contact with others who ski or ski near you or when you plan a trip to a mountain, it tells you who else is also going is a brilliant idea. My friends have a large group of people who come with us occasionally and often they get butthurt bc they arent specifically invited. An activities based site/app could cater to this as well. You could have a friends list that would be able to receive invites ect, or a public notice/invite that anyone could send out for ride share, learning a new sport, activity ect. This idea is more of a way to meet people who you share interests with or who partake in activities you would like to learn. (so if you are new at kiteboarding and you are going to traverse city this weekend kiteboarding and you would like to meet others who also are doing that in traverse city this weekend, this site could provide an outlet to expand your network of buddies who all do sweet shit
I guess the whole premise is to expand your social network with individuals who enjoy the same extracurricular activities as you and not so much keep you updated on your second cousins political opinions. Like I said facebook has its place but it doesnt promote growth in our hobbies which i think is way more important to me.
