I would say to not fish for votes so much with post tags and by tagging people. You may get some votes from that, but do you want human interaction? Comment on posts you enjoy and build connections with people. They may then support you. Try to make it fun and don't worry too much about the rewards to start with. They will come in time.
Do use your votes on those who need them (not me) and don't worry about curation rewards as you cannot make much with so little sp. You can do ten votes each day to allow the voting power to recharge.
Try have at least one new post each week so there is always something for people to vote on.
Powering up all your rewards will increase your vote.
Enjoy it.
