Should I be using REL UGC/SPONSORED yet?

Started using sponsored the week it was announced. I cant quite get my head around how fine graining the outbound links is going to make much difference but if that's the new standard then so be it, I will do as google recommends. Less for them to moan about I guess that way 😀

I think it was John Mu just said at Pubcon (Marie Haynes live tweeted the Q&A session) that there is no advantage to publishers to do it, it just helps Google understand the web better.

I think implementing UGC on blog comments will be useful though. I think basically where ever appropriate UGC replaces nofollow.

I also think the nofollow links not being nofollow any more will be quite a huge event I think it is responsible for quite a lot of changes already and I don't think the industry has fully grasped the significance of this.

Curious, would you guys just start using rel= UGC right away, or hold back and see what people discover?

Personally, I'd just go ahead and just use it right away for outbound links. I don't feel any negative implications from specifying this on outbound links. 

Thoughts?
