Whitney Matheson's Pop Candy mentions our favorite slayer and her first undead love in a section on how to do couples right. Willow and Tara also get a quick shout out. Potential West Wing or other non-verse spoilers for those not up to date on the shows in question.
Then again, I wish more shows would learn from the series that managed to achieve the impossible and make coupledom work on the small screen. Buffy and Angel, for instance -- and I hate to always bring Buffy into this, but it's true -- managed to be even hotter once they got together. (Ditto for Willow and Tara.)
