Speaking for myself, I think I'll stick around.  The good thing about this platform is that even if you don't invest anything, you can still voice your opinions, learn from others and establish human networks. Tenure in the platform, even if you don't post much but at least keep an active voice, will inevitably transform itself into higher SP and higher rewards. I would be stupid to stop and let my account die, even if at this time I don't feel too enthusiastic to make my blog bloom. 
I believe that crypto currencies and block-chain technology are here to stay and I plan to learn as much as I can and teach my kids in the process, so they grow in this environment and can enter and play the game well when they are of age.
