No, it is not like facebook so far as voting is concerned. Every time you vote, your voting power is depleted, and everyday, it recharges by 20%. You can check your voting power here: www.steemd.com/@eliry

Also, when you find a good post and want to upvote, try to do this after 30 minutes of its posting. If you upvote it before 30 minutes, all rewards will go to the author, but if u upvote it after 30 minutes, you will get curation reward by the end of 7-day payout period.

Really? after 30 minutes is better? i read the opposite just now on a blog.

Why there are a lot of people with so much votes in few minutes? And what is it the number 25 beside my name? why for some people is under 25?
I'm sorry, a lot of questions

That is your reputation score. Post some blogs or pictures so you can increae yourr reputation score if u get votes.

Perfect, thanks!
