These are great tips, unfortunately I am still stuck on 1c and I went through a rough patch where I wasn't able to be on steem as often and it has hurt my long term goal of reaching 500sp.
Currently I just nominate to the curation trail for TA. That way I know TA members are still being upvoted and earning but I don't believe I get curation out of that.
I might have to look into selling upvotes once my acct grows a little.
You'll see curation rewards for any voting activity that you do, so the TA autovotes count. :)
