It has lots of useful info.

It takes time to get followers. You want lots of followers. Here's what worked for me when I got started.

Keep at it. Don't give up. It's really tough at the start but if you keep posting good interesting stuff, lots of your own photo people will respond.

Unless you buy a lot of SteemPower you will have to write a lot posts until you earn enough Steem Power that voting is profitable. Usually around 2,000 and good voting habits you can earn a couple dollars a week by curating.

Hope that helps. Find me if you need more help.

Good Luck
