Hopefully, an intelligent one. Our content needs to be good.
I think that on Hubski it would be a lot harder to dig yourself further in, away from the popular meme/picture posts. On reddit you can simply unsubscribe from certain subreddits but here anyone can tag anything as they please and you can't bury bad content. Hence I feel like eventually we will have 14 year olds posting memes or shitty pictures under #photography which would be hard to escape.
When you click on a users name a shadowbox pops up. On the left you'll see in red: ignore user. If you find someone continually posting content you dislike, use that button.
But then doesn't that raise the issue of not knowing what good is? Your good may be somewhat bland for someone else. But I guess that's where the hashtags and such come in to play.
