Welcome back @roxane.
Most of the work that went on Steem are backend stuff. Things that will take Steem to another level (i.e.: Ressource Credit, Mira, Separation of Wallet with publishing, Security tips etc...). The community is still strong and many have stood up to take the challenge of building Steem sidechain so that everybody can create a token and makes it work like steem. I mean @steem-engine with SCOT Project. Competition in blockchain social network is also gearing up and we will see how the community react to it.
Yes, 1 year out of blockchain, is like 10 years life. Even 3 months now is like whooooooo....but don't FOMO too much :-) the mainstreet is not there yet.
