Searches that require some context are often a lot easier to find. Like, if I'm searching for something D&D related, I rarely have to specify that that's what I'm looking for. If it's on wikidot, it'll come up right away. Even for pretty generic words like 'web' or 'death', it knows I'm looking for the spell on the one hand and the cleric domain on the other, just because I've searched for so much D&D stuff and done so over and over again.

For mail I use Proton, for backup I use iDrive. I'm pretty happy with both.
