A colleague forwarded me an email about Elsevier's social bookmarking service. It's eye-candy index is definitely 2.0. I haven't signed up as yet, but have read through this "kinda" review, 2collab: A review, kinda. This was written in late November, it may be that some of the reported bugs have been ironed out by now.
One thing I have noticed is a lack of RSS feeds.
I'll put this on my list of things to investigate.

And there was no autodiscovery link in the page so my browser didn't alert me. It just goes to show how dependent I've become on IE's 'whistle' telling me when RSS is available.
Not heard back from them. :)
As more people like as well as share, the more direct exposure you receive. All without added effort from your advertising group. The key is to set up your profile and also bookmarking project well, and afterwards delight in the return.
