I'd rather have an beautiful and functional app tray than (ugh) icons on my desktop, thank you very much.

I was a user of StumbleUpon at one point. I don't think I ever had an account on Digg.

Candela Obscura might be up your alley as well. I haven't watched yet, but it's an original game and episodes are only 30 minutes.

I played a monk with Hunter's Mark provided as a once a day racial feature, and it was an absolute blast except when I lost concentration. ლ(ಠ益ಠლ)

Cheap handheld advanced medical scanners like tricorders.
