I agree sometimes it seems like overload of content.

I find its good to follow lots of people I find interesting. That way my feed has stuff I know I will like and I don't follow a ton of people so there isn't an overload of content.

Plus I have lots of time to browse my favourite tags and see what hot and find new authors and content.

You have to be active and leave lots of positive feed back and vote ur maximum daily.

It's a lot of the little things you do aside from posting that get you votes as much as the post it self.

Keep at it
