I do a blend. Some all paper, some all digi, and some hybrid. It comes down to how you define "hybrid." A LOT of what I do, even for paper scrapping, is done on the computer - I edit and sometimes seriously alter photos, do all of my journalling that I print out on good paper, do a lot of my titles, and design things that I cut out with my Gazelle, which is a computer-driven electronic cutter. The titles and journalling I play with a lot, I have tons of different fonts, I use different colors and apply various layer styles and effects in Photoshop. I also make my own background pages that I have printed as a 12x12 photo and then add paper scrapping on top of.
Here's a great (to me ) example, the background is from a digi kit, the three animal photos in the corner are mine, I added a frame from another digi kit, printed it, and added the other three photos, the title and the wooden sign.

Hybrid scrapbooking has so many benefits! You can get products in a pinch without having to go anywhere, print them and use them right away. The Webster's Pages collections are all available in high quality digital and there's a ton to choose from. I really like their Sweet Notes collection. They've been featuring digital and hybrid ideas on their blog all week and are having a giveaway tomorrow.
...also, another benefit of doing hybrid layouts is that you get to have all your favorite designs on your computer to use online.
