Is anyone currently taking advantage of the Capital One Offers page?

For about a month now, offers have been in the form of point multiplier earn (when shopping through the portal) or flat rate point earn in lieu of cash back. Some were very lucrative at the very beginning, apparently. It looks like some offers may still be worth chasing, BUT - the tracking of this system is haphazard at best, and many of the top-top earning offers have since disappeared.

I do have to wonder, however, when some sort of significant downgrade will drop (Plaza Premium notwithstanding). We'll see...
