Pretty hectic, and no way I could manage it all if I was working. Would probably need to automate a lot more and I'm actually enjoying the manual curation side more at present.
busy throws you a vote if you use their front-end and tag busy - it could be the case though that it's better value for you with other tags - nice! :)
I always try to do manual curation but lately I been thinking on automating some. My first alt will likely be for doing just that. I will have to give Busy a try one of these days.
