This is a crosspost from the hubski reddit, and I am also a redditor coming over to hubski, but these are a few general suggests that I think might make the site a bit more user friendly.
subscribing to a tag should be as easy as subscribing to a subreddit
It's annoying to have to confirm that I want to follow a tag when I click it. It's not a big problem, but it's a main problem that I have had with other services similar to Hubski in the past. They take simple things and make them just slightly more complicated then they need to be.
also: when you open a tag in a new tab you should be able to see a page for that tag I.E. That little dialog that pops up when you click on a tag to subscribe should be what shows up in a new tab if you were to right click and open it in a new tab.
When you are to tag a post when you submit it, it should automatically catch onto the tags. Sort of like in tumblr or omegle when you ad an intrest and place a comma it's demarcated as being different. It's just a little user feedback thing that might make the sight a little better
I like the idea of a downvote, but a better way to show it might be to make the downvote also hide the comment. it would be more like instead of a downvote, it's a hide button. One of the best things about reddit is giving those with nothing to say a democratic voice.
Again, I think this place is pretty neat, but I also want to make it better.
