Yes, just click on the "Give Lingot" button next to my comment. Then, click "Ok" on the following page that pops up.

You cannot give lingots directly to your followers. However, you can give lingots to those who comment or post discussions. All you have to do is click 'Give Lingot' option

You can only give lingots through comments/discussions, though maybe in the future a feature will be added so that people can be given lingots directly on their profile. :)
