hive does have some of that feeling when internet was not cool, and you had to invest some effort to use it. in the beginning for me it had a bit of that old forums feel. if you stay you will for sure find some interesting people. engagement is sometimes low but i find it it has more essence than fb or instagram.

crypto part with keys and stuff can be a bit hard, my recomendation is to check out Hive Keychain extension for your browser and try peakd.com as a front end. also when you get around keys, you could check out dapplr for mobile. it is a brand new app, looks nice, still have some bugs but it is a work in progress.
Also check out communities, maybe you find something you like.
