I feel your pain, man! Becoming fully aware in the platform enough to actually cast my vote in an intelligent manner is something that happened only recently.

The good news is that it happens pretty organically as you read articles and participate in discussions. You'll get a better and better sense of who is legit and who isn't.

For my own part, @jesta (really awesome developer behind Steem Stats and ChainBB) and @roelandp (guy who organizes Steemfest) are among my favorites at the moment, but I get the sense that in six months I'll have an even better sense of who to vote for.
