Yes, I believe we need less delegations and more manual curation. I try my best to do so, keeping almost all my voting power for my own curating efforts :))
And, obiously, each author should find the communities that suits them the best and engage within them. That's both the key to personal and network success in the long term.
Unfortunately, I see a lot of small users delegating the big majority of their stake to other projects. This only leads to a centralisation of curation and even more responsibility to the small number of manuel curators out there.
Precisely :) The more HP you have, the more responsibility you feel :)
