It's basically forced labor at this point, disgusting stuff. Off-topic, but are more generic tags preferred here? I'm just dipping my feet in the pool so I don't know all the ins and outs yet.
I've always been of the opinion that tags are both editorial and categorical. What we've implemented here is "community tags." In the upper left hand corner, next to your name is a "hub wheel" and once it does a full rotation, you will eventually have the ability to add "community tags" to any post. If you have any other questions, let me know... and welcome to Hubski!
So for instance this post should be tagged #sports and #soccer, but then might have a community tag of #worldcup or #fifaworld cup or whatever? Moreover, is there a FAQ available yet? Thanks! Edit: Imagine that, hubski.com/faq...didn't even think to try...
Also, take a look at the bottom bar on your page. Lot's of interesting info there FAQ/ABOUT and a Tutorial. Also, TMI is pretty cool. Good luck! Let me know how else I can help. -seriously.
I tagged it sports purely to increase the number of people who saw it. If you check the tags page up top you can see how many people follow the most popular tags and so on. Each post gets two tags of your choosing and then a third community tag can be added by whoever feels like it. You can tag anything whatever you want, it's the choice between specificity and reaching a wide audience that makes it interesting!
