The $0.02 Dust Threshold applies on short form (snaps, waves, threads) too.
If you really want to reward the recipient of your vote, you have three options:
- Vote with enough VP
- Use @dustsweeper, a paid service which adds value to your dust votes
- Use @dustbunny
I have used dustsweeper for years.
Good for you, and for the upvote recipients:)
